Abstract
Keywords - vehicle engineering, suspension system, mathematical model, coordinate transform, analysis of simulation
Coordinate transform is firstly used to establish ride comfortable mathematical Model. Transform the model input signal into acceleration signal of the front axle and back drive axle. Compared with the traditional ride comfortable mathematical Modelnot only the calculation accuracy is improved by using acceleration signal as input signal, but also the model is more practical. The model is more available because the complex types are separated by the equivalent transformation. Correlative model and researchful method will provide theoretic reference for automobile suspension system in the future.
