| Abstract: | The law of damping is important for semi-active automobile suspension to reduce vehicle vibration. In this paper, an optimal law of damping is proposed based on minimum principle. Then the proposed optimal law of damping is calculated numerically with steepest-descent algorithm. The simulation result shows that this time-variant damping can improve the comfort, safety and stability of vehicles comprehensively. It is of significance in both theory and engineering application. |
