【 摘 要 】

Based on the movement state of straddle-type monorail vehicle and the force state of wheels, the theoretical model is established, and the dynamic simulation software is used to analyze the anti-overturning stability of guide wheels and stabilizer wheels of straddle-type monorail vehicle under pre-pressure. Three layout schemes of guide wheels and stabilizer wheels are established, and the motion state of straddle-type monorail vehicle under three schemes is compared and analyzed. It is found that the motion state of monorail vehicle is mainly limited by the rolling stiffness and the shaking head stiffness of the vehicle itself. By increasing the rolling stiffness, the roll angle of the vehicle can be reduced, so as to reduce the load variation and speed difference of the running wheels and reduce the wear of the running wheels. Over-increasing the shaking head stiffness can reduce the side slip angle of the running wheels, so as to reduce the side slip of the running wheels and reduce the wear of running wheels.
