摘要 本文研究了可倾式车辆曲线通过时的动态特性和车体姿态控制问题。在轨道动座标系下,采用绝对座标多体动力学方法,列写动力学方程,求解逆动力学问题得到开环控制方式驱动器的输出控制力和位移,对车辆进入曲线时的倾斜滞后,提出了修正方案,并计算出最大允许滞后时间,通过对倾摆控制失效、滞后1s和滞后修正3种工况的仿真计算,得到车辆未平衡离心加速度、轮重减载率、倾覆系数、吊杆力等一些定性和定量的结果,为新型高速车辆的设计提供依据。 In this paper,the tilting vehicle'S dynamics behavior and control strategy on curye negotiation are studied. Absolute coordinate method of multibody dynamics is adopted to establish the system equation,which counts in the inertial force of moving base.The output force and displacment of actuator are calculated using inverse dynamics method.The force acting on rail and tilting mechanism is also calculated. Simulation are made under three conditions when the mechanism fails, delays for 1 second and delays with modification.Some results can be used in the design of new vehicles.
