Design of cam for potential-energy driven vehicles based on ADAMS
According to the propositional requirements of the Seventh National College Students Engineering Training Com-prehensive Ability Competition,in this article the reverse design of the cam is introduced,and the mechanism of rack and pinion are controlled by the cam to ensure that the potential-energy driven vehicle is steering smoothly.The theoretical trajectory of the potential-energy driven vehicle's front wheel is designed,and the vehicle's transmission mechanism and steering mechanism are analyzed and designed.ADAMS is used to set up the model of the vehicle's steering mechanism;efforts are made to drive the steering mechanism through the front wheel's motion trajectory;the position relationship between the rack and pinion and the cam's contact point is derived.The theoretical contour is obtained indirectly,and then the actual contour is identified through UG envelope processing.Through the physical model's production and operation,the potential-energy driven vehicle has good trajectory consistency,which has verified that this method is rationale.
