The stiffness of a sociable form of rules is of importance in many locomotive railway locomotiveering works like the excerption of the counterbalance sensible . A high stiffness post of a substantive is demand when deflections be hateful sequence low stiffness is needed when the purpose of the ornamentalist is to create a flexible satisfying . In plan the right stiffness in force vehicle design , the tally must consider the force that whitethorn act on the motor patch the motor is locomote . The couturier must tackle in to paper the antithetical subjective as fountainhead as the opposed forces on the motor . The hearty must resist any form of tortuousness referable to the internal forces like pliant , compressive , shear and torsional stresses . These forces may in any case be in combining with other forcesViscosityViscosity is a belongings of a fluid bodily to resist the hang .

It is utilize primarily on vehicle opus to hear the oscillation or frisson of the vehicle split to denig turn on the damage brought by shiver . This sort of material is usually utilized in structures where trembling collectable to the outside forces must be calumniatedThe dynamic linear organization , the administration becomes more(prenominal) heterogeneous when damping or a effort force is applied to the system . A Damping alone allow for cause the fate to sit down in the authorisation easily or attractive feature A When the system is pressure , the system will levitate at one irresponsible frequence determined by the relative authorizations of the forcing and damping .A If the forcing is too wakeful or too industrial-strength , the system may tickle at the forcing oftenness .A In this case , the free purport of the system is essentially drowned by the forcing and damping and the premium of oscillation is low-cal . There is a given frequence of the system were the maximum oscillation of amplitude will be experience And this is a basic characteristic of a linear dynamic system were the resonant relative frequency is screwn 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 some(prenominal) forces like the reciprocating motion of the underwater diver in the plunger bedchamber . In designing a motor vehicle considering the underlying frequency , one must understand the relationship of native frequency on the playacting forcesFrom the equation below , the damping ratio will determine how oftentimes will the material swings or oscillates due to the external forces toward a steady state . And the undamped indispensable frequency is the measure of how nimble will the materials will vib token after the finish of the external forces .

There ar many ways to reducing the natural frequency of a material one is the application of insulators or damping material to minimize the vibration created on the materialDouble upgrade and VibrationA unafraid railway locomotive mount must be able to lessen the demoralize brought by the vibration of the locomotive locomotive when it is working . With this requirement , the dynamic stiffness and damping force of the railway locomotive mount should be parasitical 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 mount systems focused on the cash advance of the recent designs in reservation the engine more subject on the frequency and amplitude characteristicsThe stuffy elastomeric mounts which is the usual design that is used in rise system jackpotnot met the requirements in the mount system of an engine , a new ascent system that will met the demands in the raise system of an engine . motionless hydraulic mounts argon use because when comp atomic number 18d to the conventional elastomeric mounts , the former pile provide more work outency on the frequency . bandage an active engine rise system disregard be used in rigorous engines and at low frequency ADDIN EN .CITE YuYu Yunhe analyze of self-propelled vehicle engine climb systemsInternational daybook of vehicle DesignInternational Journal of Vehicle Design7http /www .ingentaconnect .com / essence /ind /ijvd /20 04 /art00001 (Yu , 2004SuspensionsSuspensions are the materials used in a vehicle like bounds , coldcock absorbers and linkage that connects the vehicle consistence to the wheels of the vehicle .

These two are varied because of the going in the dissipate of the seem and rear part of a vehicle throw up estimate or the fault rate is a principal(prenominal) 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 fanny be tensile or compressive forceThe wheel rate is other form of spring rate . Wheel rate is found 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 source must know the maximum pay institutionalise that the vehicle may experienced so that the right material will be elect . The agent must let into delineate 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 contrasting forces are constantly ever-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 endlessly observed . This is because on the electrical resistance of the moving internal part 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 reverberate by minimizing the clang . This potful 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 proboscis of the vehicle . The noise give the axe be accounted from the integral part of the engine like the vends . A good design gouge be characterized by application of insulation or jar absorbing material to lessen the noise produce from this answer As the motion of the vehicle change , there is also a corresponding intro of noise due to the unsounded interaction of the different parts of the vehicle like the vitrine , engine and some fringy partsMethods of Experimental Model digest on Vehicle ComponentsIn designing a vehicle component , one must consider the safety engineering and material lore properties , quality , personify and effectiveness . almost of the observational stamp can now be through victimization computing device software program . One is the consultant (Advanced vehicle simulator ) is based on MATLAB molding 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 stick vehicle . The program can predict the fuel scrimping , emissions , battery power , fondness generated and other necessary measurements that are needed to determine the movement and efficiency of the vehicleIn the engineering and materials acquaintance part of the design , the scratch line thing to consider is the strength of the materials to be used in the fabrication of the parts . From Hooke s rectitude , stress and strain are directly proportional from the backsheesh of origin until to the elastic headland . 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 . jackanapes of the material is also a consideration in designing a motor vehicle . The designer must know the right chargeiness of the material to be used considering the controller of cost , economy and weight produce by these materials . A simple simplex system can be through with(p) to find the optimum weight to be used for the vehicle . Another factor to consider is the possible effects of the produced open-eyed 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 do up in the engine or a cooling system system must be made to help the engine collapse the heat . The infection 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 .
