Abstract

The invention discloses a simulation method and system of an automobile power tailgate. Based on the joint simulation design of kinematics and dynamics, model calculation is conducted with mechanical property parameters of the tailgate and external load parameters as input parameters, the fact that the tailgate hovers at any angle as a target function and the fact that manual operation force is minimized at the minimum relaxation rate of a spring as a constraint condition, and mechanical property output parameters meeting the model constraint condition are obtained. The input mechanical property parameters include tailgate parameters, motor parameters, screw parameters and / or reducer parameters, the external load parameters include manual operation force and anti-pinch force, and the output mechanical property parameters include parameters of a pole, parameters of the spring and installation positions of upper and lower spherical hinges on the pole.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more specifically relates to a simulation method and system for an electric tailgate of an automobile. Background technique [0002] Automobile electric tailgate is an important part of the car, mainly composed of tailgate, electric strut, strut mounting bracket, electric self-priming lock, ECU and other components, its main function is through the tailgate switch button on the body or the remote control key The tailgate switch button on the car can realize the automatic opening and closing of the tailgate of the car. [0003] For SUV vehicles, due to the large size and heavy weight of the tailgate, when the electric tailgate meets the normal opening and closing requirements, it is also necessary to realize the hovering of the tailgate at any angle, and at the same time increase the manual operation force and anti-pinch force. requirements. Therefore, in actual production, it is necessa...
