Full-vehicle model plays a key role in vehicle handling stability simulations, and the same vehicle model does not adapt to all kinds of vehicle simulations. In the thesis, the vehicle mechanisms of an 8×4 type construction truck were appropriately simplified and the full-vehicle parameterized multi-body dynamic model was developed according to the topology mechanical map of each part. The vehicle model suitability was researched through comparing the vehicle simulation results with the test results in lemniscate and returnability simulations. The comparison results show that the lemniscate simulation errors of the steering wheel angle, yaw angle velocity and lateral acceleration amplitude of the cargo mass centre are 3.9%, 4% and 4.4% respectively, and the returnability simulation errors of the residual steering wheel angle, residual yaw angle velocity and lateral acceleration of the cargo mass centre are 95%, 77.8% and 80% respectively. The simulation and test results all show that the lemniscate simulation errors are smaller than the returnability simulation errors because the model input was the steering wheel angular displacement in lemniscate simulation while the model input was the forces caused from the road and vehicle movement in returnability simulation. In brief, there exist significant error variations for the same vehicle model in different simulations.
