Linear dynamics is a sub branch of dynamics that deals with the find out of those organisation that is affected by parameters manage pack , hardness , viscosity , and hysteretic damping in which the crash increases linearlyFrom the references , the best way to formulate the linear dynamics is by examining the motion of an object glass in an oscillating forge . In this tending(p) example , the long suit on the start lurchs as the displacement re proceedion or the change in position change too . And t here(predicate) is an obtain increase linearly with the displacement by a mapping k . the factor k is cognise as the spring constantMotor fomite Design exploitation Linear Dynamics System in that location atomic number 18 many factors to be considered in conniving a analyse fomite But the center of discussion allow for be on the role of linear dynamics carcass in ruleing a labour fomiteMassFirst to consider is the role of fold in the design .

Because mass has direct family with the force developed by a touching object , the mass must be designed in such a way that the mass of the vehicle will create constant force performing on the vehicle thus making the vehicle changeless while the motor is runningStiffnessThe most important servant in designing a vehicle motor is the safety . In this consideration , the most appropriate factor to consider is the rigorousness of the motor . Stiffness is the resistance of an object to deflection imputable to the use force , the somatic maybe elastic in nature . Stiffness of a clobber fecal matter be measured by dividing the force applied over the displacement of the corporal from its original positionF kxwhereF is the force exerted by the object (newtonsk is the inclementness ratio (Newton per meterx is the displacement from the original position (meterStiffness has direct relationship to the elasticity of a material . The cruelness ratio using the elasticity of a material which is also known as the modulus of elasticity rear be examined from the equation belowk AE /Lwherek is the stiffness ratio (Newton per meterA is the argona of the object (meter2E is the modulus of elasticity of the materialL is the length of the material (meterKnowledge in the stiffness of a material is a basic consideration in many locomotive railway locomotiveering applications . The stiffness of a social system is of importance in many locomotive railway locomotiveering works like the selection of the right material . A high stiffness property of a material is required when deflections be hateful while low stiffness is needed when the purpose of the ornamentalist is to produce a flexible material . In designing the right stiffness in motor vehicle design , the condition must consider the force that may act on the motor while the motor is locomote . The couturier must take in to account the antithetical subjective as well as the foreign forces on the motor . The material must resist any form of tortuousness due to the internal forces like tensile , compressive , shear and torsional stresses . These forces may also be in combination with other forcesViscosityViscosity is a property of a fluid material to resist the hang . In fluid mechanics , a simple mucilaginous cling which is characterized normally by a uniform flow will have a possible condition if solo the formula of the Reynolds s number is less than 60Re ?vL ?60where?is the density of the retarding fluidv is the speed of the object relative to the fluidL is a characteristic dimension of the object?is the viscosity of the fluidThis is a prerequisite for the viscosity to be uniform and it is not usually met generally for oscillators , and some of the recent studies show that the damping of nisus drag is directly proportional to the squ atomic number 18 of the velocity of the moving air . This is just one example of how two or to a greater extent damping types must sometimes be folded into an adequate dumbfound of dissipation .

It is used primarily on vehicle parts to date the oscillation or vibration of the vehicle parts to denig excite the damage brought by vibration . This sort of material is usually utilized in structures where vibration due to the outside forces must be minimizedThe dynamic linear system , the system becomes more(prenominal) complicated when damping or a driving force is applied to the system . A Damping alone will cause the component to sit down in the potential well or attractor A When the system is forced , the system will oscillate at one absolute frequence determined by the relative strengths of the forcing and damping .A If the forcing is too weak or too industrial-strength , the system may oscillate at the forcing frequency .A In this case , the free movement of the system is essentially drowned by the forcing and damping and the amplitude of oscillation is weak . There is a given frequency of the system were the maximum oscillation of amplitude will be experienced And this is a basic characteristic of a linear dynamic system were the resonant frequency is known by determining the damping force and the rude(a) frequency of the system . ADDIN EN .CITE PetersRandall D PetersDAMPINGMercer Universityhttp /physics .mercer .edu /hpage /damping .htm (Peters , 2007Natural FrequencyNatural frequency is the vibration of a material when an outside force acts on the material . When a motor moves , the motor experiences internal frequency due to the fulfil of several forces like the reciprocating motion of the diver in the piston chamber . In designing a motor vehicle considering the inherent frequency , one must understand the relationship of natural frequency on the acting forcesFrom the equation below , the damping ratio will determine how much will the material swings or oscillates due to the external forces toward a steady state . And the undamped natural frequency is the measure of how fast will the materials will vib footstep after the application of the external forces .

There are many ways to decrease the natural frequency of a material one is the application of insulators or damping material to minimize the vibration created on the materialDouble mounting and VibrationA unafraid railway locomotive mount must be able to lessen the appal brought by the vibration of the engine when it is working . With this requirement , the dynamic stiffness and damping force of the engine mount should be leechlike on the amount of frequency gene posed by the engine as well as the amplitude of the engine . Because of these considerations , the design of engine mounting systems focused on the improvement of the recent designs in making the engine more dependent on the frequency and amplitude characteristicsThe conventional elastomeric mounts which is the usual design that is used in mounting system jackpotnot met the requirements in the mounting system of an engine , a new mounting system that will met the demands in the mounting system of an engine . Passive hydraulic mounts are use because when compared to the conventional elastomeric mounts , the former can provide more dependence on the frequency . While an active engine mounting system can be used in rigid engines and at low frequency ADDIN EN .CITE YuYu Yunhe analyze of automotive vehicle engine mounting systemsInternational Journal of Vehicle DesignInternational Journal of Vehicle Design7http /www .ingentaconnect .com /content /ind /ijvd /20 04 /art00001 (Yu , 2004SuspensionsSuspensions are the materials used in a vehicle like spring , coldcock absorbers and linkage that connects the vehicle body to the wheels of the vehicle . The chief(prenominal) purpose why recesss are built for a vehicle is that , to contribute to the vehicle s handling and braking purposes so that a good quality and safe driving will be deliver the goods and also to make the occupants feel comfortable while they sit down in to the vehicle . There are two kinds of suspension , the front end and rear suspension .

These two are different because of the difference in the shoot of the front and rear part of a vehicle flush rate or the suspension rate is a main ingredient in making the vehicles ride eyeshade or the location in the suspension stroke . Spring rate is the ratio means to measure how the spring will resist on the force exerted by the essence . The force can be tensile or compressive forceThe wheel rate is another form of spring rate . Wheel rate is based on the effectiveness of the spring rate turn up on the wheel of the vehicle . From experiment , the wheel rate is somewhat less than the spring rateIn the design of the right kind of spring , the designer must know the maximum load that the vehicle may experienced so that the right material will be chosen . The designer must take into account also the difference in the loading of front and rear part of the vehicle . Then is the distribution of the load so that the designer may know where to put the suspensionsAlso , the designer must consider that different forces are constantly changing as the vehicle moves . These forces maybe internal or external are dependent on the motion of the vehicle . They are directly proportional thus the higher is the velocity , the higher is the force experienced by the vehicleNoise controlNoise in a vehicle while moving is always observed . This is because on the resistance of the moving internal parts of the vehicles on clank Examples of these moving parts are the piston and cylinder . The reciprocating motion of the piston on the cylinder produces some encumbrance The designer must take in to account on how to minimize the noise by minimizing the friction . This can be achieved by applying lubrication system to the piston and cylinder system . Another noise that is created in a vehicle is the vibration on the motor body of the vehicle . The noise can be accounted from the integral part of the engine like the gears . A good design can be characterized by application of insulation or shock absorbing material to lessen the noise produce from this event As the motion of the vehicle change , there is also a corresponding creation of noise due to the fundamental interaction of the different parts of the vehicle like the casing , engine and some peripheral partsMethods of Experimental Model Analysis on Vehicle ComponentsIn designing a vehicle component , one must consider the safety engineering and material lore properties , quality , cost and effectiveness . Some of the experimental stamp can now be through using computing device software . One is the consultant (Advanced vehicle simulator ) is based on MATLAB modeling tool which enables a designer to simulate a conventional , hybrid vehicle . Some of the characteristics of the output of ADVISOR are the mathematical operation of the model vehicle . The program can predict the fuel economy , emissions , battery power , warmheartedness generated and other necessary measurements that are needed to determine the performance and efficiency of the vehicleIn the engineering and materials science part of the design , the first thing to consider is the strength of the materials to be used in the fabrication of the parts . From Hooke s Law , stress and strain are directly proportional from the point of origin until to the elastic point . The designer must take into account the different force acting on the materials so that the designer can depend the maximum stress that the materials can be experienced . From here , the designer can choose from a catalog permit say steel that is most appropriate from the given stresses . lightweight of the material is also a consideration in designing a motor vehicle . The designer must know the right weight of the material to be used considering the restraint of cost , economy and weight produce by these materials . A simple simplex method can be done to find the optimum weight to be used for the vehicle . Another factor to consider is the possible effects of the produced light up due to friction to the engine parts . As the vehicle moves , the engine parts generate heat due to friction . The material must resist the heat build up in the engine or a cooling system must be made to help the engine collapse the heat . The transmission and gearbox must also be examined so that efficiency can be achieved as the vehicles moves . rubbing must be minimized as the gear moves . This can be achieved by applying lubrication system as well as cooling systemReferencesADDIN EN .REFLIST (2000 ) An Introduction To System Dynamics - Second SystemsPETERS , R . D (2007 ) DAMPING .
