To speed up the virtual development of the automobile, Using VC++6.0 programming environment and the function of ADAMS could execute the batch files; the simulation and analysis of automotive system are developed. A friendly convenient and the flexible man-machine conversation interface are developed by VC++ foreground. The parameters input by users and ADAMS operating commands are encapsulated in acar.cmd file. ADAMS will automatically calculate and simulate after executing the acar.cmd file. It can be showed that this program will improve the study and quicken the design of vehicle progress greatly.
