Vehicle ride comfort determines vehicle performance, affects the ride comfort and reliability. Aimed at the problems in establishing the vehicle dynamics model by traditional classical mechanical methods, the vehicle ride comfort simulation analysis scheme on the basis of virtual prototyping technology is put forward. Based on Multi-body dynamics, the virtual prototype vehicle model was established. According to the national standards, the vehicle ride comfort simulation scheme was designed, including the simulation test with sine wave excitation, the simulation test on triangular bump road and random uneven road. Through the test, the root mean square of weighed acceleration can be got and the evaluating process can be accomplished according to the ISO standard. The results show a good ride comfort of the testing vehicle. Virtual test provides a useful reference for the complex mechanical product design of physical prototype.
