电驱动铰接车本身质量偏置对转向操稳性的影响
Effects of mass offset on steering handing stability for electric-driven articulated truck
摘要
Abstract
A roll and centroid offset steering kinematics model was presented according to the electric-driven articulated vehicle structural characteristics. The theoretic relationship between the yaw rate and roll angle steady-state value was established and the centroid position offset to the handling stability effects in steering conditions was discussed by calculating the yaw rate gain, roll angle gain and understeer parameter. The results show that analysis and test results are basically consistent when the articulated vehicle is steering at different speeds; the relationship between the yaw rate and roll angle is a complex nonlinear. And the centroid offset has different influence on the articulated vehicle handling stability. It provides a theoretical reference for the integrated control of articulated vehicle handling stability.关键词
