Analysis of K&C performances on vehicle suspension

As a means of transportation,automobiles have been integrated into most people's life,which suspension system is an important part.The suspension system with better comprehensive performance has great significance in improving the ride comfort and handling stability.Vehicle dynamic model is established,on which a model for the whole vehicle is simplified and quarter kinetic model for the suspension is obtained.After theoretical analyzing of the main parameters KC for affecting ride comfort,an expression for describing nonlinear characteristics of suspension parameters are adopted with the method of subsection,which provide ideas for studying performances of vehicle and at the same time further understanding of time domain response of non-linear characteristic of suspension system.
