Study of The Influence of Guide Wheel Preload on The Dynamic Performance of APM Vehicle
In this paper,the structure of APM vehicle bogie is analyzed,an APM vehicle dynamics simulation model is established,and the influence of the preload change of the guide wheel on the passability and running smoothness of the vehicle curve is analyzed.The results show that the pre-pressure setting increases the radial force and guiding torque of the guide wheel,and the guiding performance is poor.If the pre-pressure is zero or there is a gap between the wheel and rail,the radial force and guide moment transient response of the guide wheel will be too large,and the vehicle running attitude will swing left and right;The maximum lateral deflec-tion force of the walking wheel increases with the increase of the pre-pressure of the guide wheel.A zero pre-pressure of the guide wheels or a clearance between the wheels and rails can lead to deterioration of the vehicle's lateral smoothness.Comprehensive consideration,the guide wheel should be set with a certain pre-pressure,but not too large,recommended pre-pressure 600 N～1800 N.
