【Abstract】 A dummy prototype model of a high-speed bus’s air suspension is established by using the AD- AMS software.Also the dynamic process of the wheels which move on different road surfaces is discussed through several kinematical simulations by choosing different data of the main parameters of the model and the data which got from the simulated process is analyzed to derive the regressive equations.Moreover,the com- patibility of system parameters by using the similitude theory is confirmed.Additionally,shorten the model in scale of 4:1 to simulate the dynamic process.Last but not least,the paper compared the simulation result with the result of the prototype simulation.It is not difficult to fred that the similitude theory is feasible.This method saves the product design time and reduces the design cost,providing other similar products some new design ideas at the same time.更多还原
