1. 研究目的与意义(文献综述)
vehicle suspension connects wheels and theframe or vehicle body, which directly conveys all forces and moments betweenthe wheel and the body. fluctuations of load must passed through the suspensionto the body, affecting the comfort of driver. in all the working situationincluding straight running, steering, acceleration, braking and so on , thesuspension controls the correct attitude of the wheel, that ensure the correct positioningparameters of every wheel within a certain changing range. it also makes sure theforce distribution between each tire and ground, so the correct design of thesuspension plays a key role in ensuring the stability of the operation.
for medium-sized cars, there is acertain amount of space for layout, and because the prices of vehicle does notneed be too low reasons, better materials can be used to meet the suspension’s materialperformance requirements. in recent years, independent suspensions are more widelyused in both of the front and rear suspension. the working characteristics ofthe independent suspension ensures the left and right wheels on the same axlecan be relatively beating independent. in the road, which is not in verysmooth, suspension can also ensure good contact of the tire to the ground. wheelswill not affect the each other, even they are in a same axle. therefore,comfort and handling stability will be better guaranteed.
