Design and dynamic analysis of the micro-suspended monorail
摘要
Abstract
A 20 degree of the freedom model of the micro-suspended monorail is established to analyze a new type of the vehicle system named micro-suspended monorail. The formula of the tire is established by using the magic formula. Through the modal analysis of the vehicle, the modes of the vehicle are obtained, and resonance has little effect on the vehicle. When the vehicle moves in a right turn curve, it yaws in the clockwise direction. Under the action of the guidewheel ( stable wheel) force, the front bogie yaws clockwise but the rear one yaws counterclockwise. Moreover, the two bogies and the car body roll during the curve passing process of the vehicle. When the vehicle speed is high enough, the left drive wheel will derail and the anti-overturning moments are provided by the stable wheels. Then, the car body yaws in the counterclockwise direction when it moves out of the curve. In the simulation of the vehicle passing the curve, the clearance between the guide wheel and rail surface will lead to a fatal impact on the bogie. At the same time, the dynamic response of the vehicle under the crosswind is tested. The vehicle will not overturn due to the crosswind. Finally, the collision of adjacent vehicles is analyzed. The results show that there is an intermittent collision force between two vehicles due to the vehicle's non synchronous pitch motion.关键词
