Abstract: Based on Pro/E, straw-checkerboard sand barriers paving robot was designed and a virtual prototype model of the robot was built by transforming model from Pro/E to ADAMS.Problems of fluid system modeling, control system modeling and operating conditions modeling of the virtual prototype model were analyzed briefly. Virtual tests with respect to ride comfort were carried out with several typical operating conditions.The virtual tests in respect of kinematics and dynamics were carried out with several operating conditions and the virtual prototype was verified by comparing the results from practical tests.
