ADAMS/Car is used as a tool to build the whole truck model. The designed truck＇s constant-radius cornering analysis and its ride performance simulation analysis under B class random road condition are carried out according to national experimental method standards. Compared the simulation results with the field test results indicate that performance index of the designed air suspension truck＇ s constant-radius cornering and its ride performance meets the design requirements and reaches its prospective target. And resuhs from simulation are similar to those from tests in value and trend, which indicates the virtual prototype is correct. The model can be used further to opti,nize suspension parameters and do some design work on the control system of air suspension.展开更多
