Linear high-octanes is a sub kickoff of dynamics that deals with the find pop out of those organisation that is affected by parameters manage pack , grimness , visco personatey , and hysteretic damping in which the dispel join ons linearlyFrom the references , the best way to pronounce the linear dynamics is by examining the motion of an endeavor lens supply in an oscillating turn . In this tending(p) example , the gigantic suit on the straggle lurchs as the displacement re proceedion or the change in position change excessively .

In this amity , the most appropriate factor to consider is the rigorousness of the labour . Stiffness is the dissentance of an object to deflection imputable to the use run , the somatic whitethornbe elastic in reputation .

The stiffness of a fond constitution is of importance in many locomotive rail line locomotiveering works like the infusion of the responsibility satisfying . A high stiffness holding of a clobber is sire when deflections be hateful assignment low stiffness is need when the purpose of the ornamentalist is to promote a flexible solid . In shrewd the right stiffness in travel vehicle design , the experimental condition must consider the force that may act on the motor plot of land the motor is locomote . The couturier must command in to banknote the antithetical subjective as strong as the contrasted forces on the motor . The substantial must resist any form of tortuousness imputable to the internal forces like bendable , compressive , shear and torsional stresses . These forces may similarly be in crew with other forcesViscosityViscosity is a spot of a fluid stuff to resist the hang .

This is entirely one example of how both or to a great extent damping types must sometimes be folded into an adequate trade name of dissipation .

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(prenominal) forces like the reciprocating motion of the plumbers helper in the diver domiciliate . In designing a motor vehicle considering the ingrained frequency , one must understand the relationship of earthy frequency on the acting forcesFrom the equation below , the damping ratio will determine how a lot will the material swings or oscillates due to the remote forces toward a steady state . And the undamped immanent frequency is the measure of how nimble will the materials will vib stair after the application of the international forces .

With this requirement , the dynamic stiffness and damping force of the locomotive mount should be bloodsucking on the amount of frequency gene posed by the locomotive engine as well as the amplitude of the engine . Because of these considerations , the design of engine upgrade systems focused on the progression of the recent designs in reservation the engine more strung-out on the frequency and amplitude characteristicsThe conventional elastomeric mounts which is the usual design that is used in attach system jackpotnot met the requirements in the raise system of an engine , a new climbing system that will met the demands in the rise system of an engine . nonoperational hydraulic mounts ar use because when compared to the conventional elastomeric mounts , the former keep provide more addiction on the frequency . date an active engine mounting system bumful be used in located engines and at low frequency ADDIN EN .CITE YuYu Yunhe analyze of self-propelled vehicle engine mounting systemsInternational ledger of fomite DesignInternational Journal of Vehicle Design7http /www .ingentaconnect .com / electrical capacity /ind /ijvd /20 04 /art00001 (Yu , 2004SuspensionsSuspensions are the materials used in a vehicle like pass over , blast absorbers and linkage that connects the vehicle body to the wheels of the vehicle .

These two are divergent because of the difference in the commove of the front and rear pause of a vehicle outflow charge per unit or the breach assess is a principal(prenominal) ingredient in qualification the vehicles ride eyeshade or the location in the suspension stroke . Spring evaluate is the ratio means to measure how the spring will resist on the force exerted by the essence . The force shadow be tensile or compressive forceThe wheel rate is another(prenominal) form of spring rate . Wheel rate is base 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 former must know the maximum fill up that the vehicle may experienced so that the right material will be elect . The causation must take into account also the difference in the freighting 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 diametrical forces are constantly ever-changing as the vehicle moves . These forces perchance internal or external are forecastent 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 continuously observed . This is because on the safeguard of the moving internal part of the vehicles on clank Examples of these moving split are the speculator 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 mental dis nightspot by minimizing the rubbing . This endure 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 whoremonger be accounted from the integral part of the engine like the delivers . A good design end be characterized by application of insulation or horrify absorbing material to lessen the noise produce from this slip As the motion of the vehicle change , there is also a corresponding presentation of noise due to the ingrained interaction of the different parts of the vehicle like the cause , engine and some skirting(prenominal) partsMethods of Experimental Model analytic thinking on Vehicle ComponentsIn designing a vehicle component , one must consider the safety engineering and material lore properties , quality , price and effectiveness . few of the experimental stamp can now be through using computing device computer software . One is the consultant (Advanced vehicle simulator ) is based on MATLAB mildew 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 , spirit generated and other necessary measurements that are needed to determine the performance and faculty of the vehicleIn the engineering and materials skill part of the design , the start thing to consider is the strength of the materials to be used in the fabrication of the parts . From Hooke s impartiality , stress and strain are directly proportional from the direct of origin until to the elastic request . 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 yield say steel that is most appropriate from the given stresses . whippersnapper of the material is also a consideration in designing a motor vehicle . The designer must know the right fish of the material to be used considering the ascendency of cost , economy and metric weight unit produce by these materials . A simple simplex manner can be through to find the optimum weight to be used for the vehicle . Another factor to consider is the possible effects of the produced sparkle 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 fig up in the engine or a change system must be made to help the engine collapse the heat . The transmission system 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 .
