Design And Research Of The Power Lift Mechanism Of Tail Door

为解决尾门电动机构的布置问题,对摆臂连杆式尾门电动机构建立了开闭过程的输出力计算模型,得到了尾门电动机构电机输出扭矩的计算方法,并通过excel软件建立公式得到了电机输出扭矩随尾门开度的变化曲线,简化了尾门电动开闭可行性的校核过程。运用CATIA DMU Kinematics模块建立了尾门电动机构的运动仿真模型,输出了空间距离动态曲线以及运动包络体作为边界条件指导设计。

In order to solve the layout problem of the power lift mechanism of tail door, the calculation model of the output force of the power lift mechanism of tail door was established, and the method for calculating the output torque of the motor was obtained. The curve of the motor torque with tail door opening angle was obtained by Excel software. The procedure of checking the electric feasibility of the tail door was simplified. The kinematic simulation model of the power lift mechanism was established by using CATIA DMU Kinematics module. The dynamic distance curve and the motion envelope were output as the boundary condition to guide the design.
