Analyze and Control on the Flexible Body of Tractor Semi-trailer Rollover

Abstract

Based on the tractor semi-trailer modal test results, a rigid tractor semi-trailer frame was built. Then the rigid one was flexiblized. Conventionally the tractor semi-trailer was used to be treated as a rigid body in lateral stability control, which differs from the actual situation. Flexible tractor semi-trailer was used to study rollover effect due to the longitudinal torsional deformation of tractor semi-trailer in emergency obstacle avoidance process.
