摘　　要：文章分析了汽车电动尾门系统和电动撑杆结构组成原理。基于某SUV车型,建立了汽车尾门系统力学模型,推导出电动撑杆输出力表达式。运用MATLAB进行仿真计算,求解出车辆在平坡、上坡、下坡3种工况下,撑杆输出力与尾门转角的曲线关系。为电动尾门系统的优化设计和电动撑杆的力学分析提供有效参考。The structure composition principle of automobile electric tailgate system and electric brace rod is analyzed.Based on one SUV vehicle model,the mechanical model of the tailgate system was established,and the expression of the output force of the electric brace rod was deduced.To use MATLAB software for simulation calculation,the curve relationship between the electric brace rod output force and the tailgate rotation angle under three working conditions of flat slope,uphill and downhill was solved.It provides effective reference for the optimization design of the electric tailgate system and the mechanical analysis of the electric brace rod.
