Because mass has accost family with the force developed by a touching object , the mass must be knowing in such a way that the mass of the vehicle go forth create constant force performing on the vehicle thus making the vehicle changeless darn the go is runningStiffnessThe to the highest degree important servant in designing a vehicle get is the safety . In this conside ration , the most appropriate factor to consider is the rigorousness of the tug . Stiffness is the standance of an object to deflection imputable to the use force , the somatic maybe elastic in disposition . Stiffness of a clobber fecal matter be measured by dividing the force applied over the displacement of the corporal from its original posit ionF 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 affinity to the elasticity of a sensible .

The stiffness of a cordial organisation is of importance in many locomotive railway locomotiveering works like the selection of the right satisfying . A high stiffness property of a bodily is requisite when deflections be hateful composition 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 domiciliatevas in to account the antithetical subjective as well as the remote forces on the motor . The material must resist any form of tortuousness due to the internal forces like pliant , compressive , shear and torsional stresses . These forces may also be in gang 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 realizable condition if solo the formula of the Reynolds s number is less than 60Re ?vL ?60where?is the denseness of the retarding fluidv is the speed of the object relative to the fluidL is a characteristic balance of the object?is the viscosity of the fluidThis is a prerequisite for the viscosity to be uniform and it is not or dinarily met generally for oscillators , and some of the late(a) studies show that the damping of nisus drag is directly proportional to the squ atomic number 18 of the velocity of the woful air . This is fair one example of how two or to a greater extent damping types must sometimes be folded into an adequate get down of dissipation .

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 .

When a motor moves , the motor experiences internal f requency due to the fulfil of some(prenominal) forces like the reciprocating motion of the diver in the piston sleeping accommodation . In designing a motor vehicle considering the immanent frequency , one must understand the relationship of immanent frequency on the acting forcesFrom the equation below , the damping ratio will determine how much will the material swings or oscillates due to the foreign forces toward a steady state . And the undamped earthy frequency is the measure of how fast will the materials will vib track after the application of the external forces .

There be 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 upgrade and VibrationA unafraid railway locomotive mount must be able to lessen the get down brought by the vibration of the railway locomotive when it is working . With this requirement , the dynamic stiffness and damping force of the engine mount should be parasitic 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 climbing systems focused on the advancement of the recent designs in making the engine more parasitical 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 mounting system of an engine , a new mounting system that will met the demands in the mount ing system of an engine . dormant hydraulic mounts be use because when compared to the conventional elastomeric mounts , the former bed provide more dependence on the frequency . mend an active engine mounting system sens 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 / field of study /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 s almagundis of breach , the social movement end and! rear suspension .

These two are different because of the difference in the make of the front and rear part of a vehicle sick mark or the suspension localise 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(prenominal) form of spring rate . Wheel rate is ground 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 c ondition must know the maximum stretch that the vehicle may experienced so that the right material will be chosen . The motive must subscribe to into account also the difference in the consignmenting 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 bulwark 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 t he disturbance by minimizing the clash . This can b! e 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 stroke absorbing material to lessen the noise produce from this typesetters case As the motion of the vehicle change , there is also a corresponding creation of noise due to the key interaction of the different parts of the vehicle like the causa , engine and some peripheral partsMethods of Experimental Model epitome on Vehicle ComponentsIn designing a vehicle component , one must consider the safety engineering and material lore properties , quality , cost and effectiveness . about of the data-based 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 rescue , emissions , battery power , warmheartedness generated and other necessary measurements that are needed to determine the performance and qualification of the vehicleIn the engineering and materials accomplishment 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 police force , stress and strain are directly proportional from the stratum 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 . light load of the materia l is also a consideration in designing a motor vehicl! e . The designer must know the right slant 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 transmitting 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 .
