Abstract
The semi-trailer chassis was usually treated as rigid body in many existing literature, which would lead to larger deviation from actual situation. A rigid semi-trailer chassis model was built andflexiblized based on the modal test results in this paper. The tractor semi-trailer withflexible chassis was utilized to simulate the rollover scenarios on high speed obstacle avoidance under emergency based on virtual prototyping. The simulation results were compared to the simplified 5-DOF, 3-wheel linear vehicle model. It was revealed that the wheels on flexible chassis are more inclined to be got pushed up and away from the road, which is likely to occur rollover. The actual roll angle of semi-trailer is proposed to be measured from several positions, and it should be a weighted value.
