摘　　要：针对机械式反操纵负载模拟器加载精度低的问题,提出了提高其加载精度的设计方法,即采用虚位移原理法对机械式反操纵负载模拟器建立负载力矩模型,利用杆件角度的变化从负载力矩模型中分析得出杆件的合理范围.通过对负载力矩模型的负载曲线做逼近处理,达到对负载力矩模型进行重构的目的.提出了利用负载力矩模型杆件角度分析与蒙特卡罗相结合的方法来设计杆件,其优点在于可找寻同时满足多级加载梯度条件的杆件组,避免了传统方法的不足,即利用最大加载角度进行优化从而导致无法模拟真实加载情形及最终找寻到的是加载梯度少的杆件组.最后,利用仿真验证了优化结果.Due to the mechanical reverse operation simulator low accuracy problem,design method is proposed to improve the loading accuracy. According to the principle of virtual displacement method,the torque and inertial torque models of mechanical reverse operation simulator were built. They were handled by means of curve function fitting tool. The integration of mechanical angle variable method and Monte-Carlo was proposed to solve the design parameters optimization in the available mechanical bar ratio range. The number of multi-type gradient links can be available when the reduced variable is applied to the design parameters of the mechanical reverse operation simulator. The proposed method avoids searching for bars in maximal loading angle the traditional way used in the parameters optimization,which can not simulate actual condition and achieve multi-type gradient links. After testifying by the simulation,the results are applied to the design of the mechanical reverse operation simulator.
