中文摘要：
针对双重功率分流系统的载荷均匀分布问题,建立了该系统的拟静力学模型,并根据系统构成功率流闭环的特点,推导出了系统的扭转角变形协调条件.将该条件与系统的力矩平衡条件和弹性支撑条件联立,并运用当量啮合误差和等效啮合刚度理论,计算出了各齿轮副传递的扭矩,最终得到了系统的均载系数.文中还从静力学角度分析了各构件安装误差和制造误差对系统功率分流的影响.结果表明,这些误差对系统的均载特性共同起作用,单独减小某一种误差,并不能达到最好的均载效果.
英文摘要：
In order to implement the uniform load distribution of the gear train with dual power split, first, a pseudo- static model is built. Next, according to the closed-loop characteristics of system power flow, the conditions for the deflection compatibility of torsional angle are proposed, which are then combined with the moment equilibrium conditions and the elastic support conditions to calculate the transmission torque of each gear pair with the help of the equivalent mesh error theory and the equivalent mesh stiffness theory. Finally, the load-sharing coefficient of the system is obtained and the influences of the installation and manufacturing errors of each component on the power split are analyzed based on the statics theory. The results show that the above-mentioned eJTors collectively influence the load-sharing characteristics, and that the reduction of a single error is ineffective in achieving perfect load-sharing characteristics.
