| Abstract: | According to the features of external characteristics of shock absorber whose series orifice is variable,a design approach of its key parameters is put forward.A mathematical vehicle model of a seven-freedom was built up and solved in order to design the key parameters of shock absorber whose series orifice is changeable.The purpose to optimize external characteristics of shock absorber is to improve the transient response characteristic,riding and wheel ground adhesion index.The results indicated that usin... |
