摘要/Abstract

摘要：

窄体车辆有助于解决常规乘用车的道路占用、空间浪费、能源危机和环境污染等问题，应用主动侧倾技术解决窄体车易侧翻的安全性问题。根据窄体车主动侧倾运动的特点，建立窄体车车身动力学模型，考虑主动侧倾特性及车辆侧向与纵向运动引起的车轮载荷变化，结合UniTire统一轮胎模型，进行主动侧倾窄体车极限态工况状态参数相平面分析，探明窄体车运动机理，获得窄体车极限态运动规律及运动特性，为提高窄体车稳定性研究奠定基础。

Abstract:

The narrow body vehicle can help to solve the problems of road occupation， space waste， energy crisis， and environmental pollution and the active rollover technology can be applied to solve the rollover risk of narrow body vehicle. According to the movement characteristics of active roll of the narrow body vehicle， the body dynamics model of the narrow body vehicle is established. In consideration of the active roll characteristics and the wheel load changes caused by the lateral and longitudinal movement of the vehicle， combined with the UniTire unified tire model， the phase plane analysis of the state parameters of the active roll narrow body vehicle under the limit state conditions is carried out to verify the motion mechanism of the narrow body vehicle， obtain the limit state motion rules and motion characteristics， which lays a foundation for further study on the improvement of stability of the narrow body vehicle.

Key words: active roll of narrow body vehicle, limit state, dynamic mechanism, phase plane
