Steering test of mid-size bus with flexible-body dynamics model

Abstract

The object of this paper is to analyze the vehicle structural vibration responses during the step steering simulation test. With computer simulations, confirming the influence from the difference between configurations of components on mid-size electrical bus and tradition one could be possible. The difference of the vibration responses between flexible multi-body model and rigid one would be discussed. Since the wheel base of mid-size bus is longer than passenger car, the deformation of vehicle body more obviously influences the output of vibration response. The operating condition in practical driving can be expressed by flexible model, and the performance prediction of vehicle can be closer to the real vehicle behavior. The difference between the flexible body simulation and rigid body simulation is 1.17%, and the flexible body model is more practical.

Research on a Multinode Joint Vibration Control Strategy for Controlling the Steering Wheel of a Commercial Vehicle

“…Consequently, it can be ignored in the analysis and used as a scattered composite rigid body for resonance suppression analysis [1]. In the last two decades, researchers have performed many studies on the approaches for the resonance suppression of structure, not only simple design models [2][3][4][5][6][7][8][9] to adjust vibration control parameters, but also dynamic vibrational behaviour of the structure [10,11]. In addition, other methods have been studied to regulate vibration responses.…”
