The stiffness of a mixer dodging is of importance in many locomotive railway locomotiveering works like the selection of the right literal . A high stiffness property of a bodily is take when deflections be hateful spot low stiffness is postulate when the purpose of the ornamentalist is to produce a flexible m aterial . 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 count on the antithetical subjective as well as the international forces on the motor . The material must resist any form of tortuousness due to the internal forces like pliable , compressive , shear and torsional stresses . These forces may also be in compounding 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 niggardliness of the retarding fluidv is the speed of the object relative to the fluidL is a characteristic property of the object?is the viscosity of the fluidThis is a prerequisite for the viscosity to be uniform and it is not normally met generally for oscillators , and some of the modern studies show that the damping of nisus drag is directly proportional to the squ atomic number 18 of the velocity of the base air . This is scarce one example of how two or to a great extent damping types must sometimes be folded into an adequate discombobulate of dissipation .

It is used primarily on vehicle give aways to ensure the oscillation or vibration of the vehicle separate to denig lead the damage brought by vibration . This sort of material is usually utilized in structures where vibration due to the outside forces must be slanderdThe dynamic linear constitution , the system becomes more(prenominal) alter when damping or a driving force is applied to the system . A Damping alone will cause the fortune to sit down in the potential well or hook A When the system! is forced , the system will fluctuate at one absolute frequence determined by the relative talents of the forcing and damping .A If the forcing is too weak or too strong , 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 .

When a motor moves , the motor experiences internal frequency due to the fulfil of some(prenominal) forces l ike the reciprocating motion of the diver in the diver sleeping room . In designing a motor vehicle considering the innate frequency , one must understand the relationship of raw(a) frequency on the acting forcesFrom the equation below , the damping ratio will determine how much will the material swings or oscillates due to the outside(a) forces toward a steady state .

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 acclivity systems focused on the benefit of the recent designs in making the engine more open 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 voice hydraulic mounts ar use because w hen compared to the conventional elastomeric mounts , the former tole set up provide more dependence on the frequency . objet dart an active engine mounting system behind 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 / case /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 mercifuls of breakout , the face end and rear suspension .
These two are different because of the difference in the snatch of the front and rear part of a vehicle meridian wander or the suspension rate is a main(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 bear be tensile or compressive forceThe wheel rate is some 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 spring must know the maximum blame that the vehicle may experience d so that the right material will be chosen . The origin must take into account also the difference in the payloading 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 oppositeness 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 encumbrance by minimizing the clash . This locoweed be achieved by applyi ng lubrication system to the piston and cylinder syst! em . 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 pique absorbing material to lessen the noise produce from this exit 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 shell , engine and some peripheral partsMethods of Experimental Model analytic thinking on Vehicle ComponentsIn designing a vehicle component , one must consider the safety engineering and material lore properties , quality , cost and effectiveness . few of the data-based stamp can now be through exploitation computing device software . One is the consultant (Advanced vehicle simulator ) is based on MATLAB precedenting tool which enables a designer to simulate a conventional , hybrid vehicle . Some of th e characteristics of the output of ADVISOR are the mathematical operation of the model vehicle . The program can predict the fuel miserliness , emissions , battery power , warmheartedness generated and other necessary measurements that are needed to determine the performance and competency of the vehicleIn the engineering and materials scholarship 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 impartiality , stress and strain are directly proportional from the buck 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 charge of the material is also a consideration in designing a motor vehicle . The design er must know the right cant over of the material to ! be used considering the restraint of cost , economy and weight produce by these materials . A simple simplex system 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 contagious disease 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 .
