摘　　要：针对在试验室条件下高效准确评估燃气舵操纵机构摩擦力矩需求,设计了燃气舵舵轴轴承摩擦力矩试验系统,在此基础上进一步搭建了操纵机构摩擦力矩试验系统,充分模拟燃气舵系统实际安装状态,进而提出了摩擦力矩试验方法,揭示了关键轴承摩擦力矩随加载载荷与过载系数变化规律,探究了操纵机构摩擦力矩关键影响因素。试验结果表明,试验系统为准确获取摩擦力矩提供了合理的测试手段,舵轴关键轴承摩擦力矩随加载载荷和过载系数的升高而增大,增加关键轴承之间的距离可以明显减小摩擦力矩,且轴承摩擦力矩在操纵机构摩擦力矩中起主导作用。In order to efficiently and accurately evaluate the friction torque of the jet vane's manipulator under the laboratory conditions,a test system for the friction torque of the jet vane shaft bearing is designed.On this basis,a test system for the friction torque of the manipulator is further built to fully simulate the actual installation state of the jet vane system,and then a test method for the friction torque is proposed,the variation trend of the key bearings friction torque with the load and overload coefficient are revealed,and the key factors affecting the friction torque of the manipulator are explored.The test results show that the test system provides a reasonable test method for accurately obtaining the friction torque.The friction torque of the key bearings of the rudder shaft increases with the rise of the load and overload coefficient,and the bearing friction torque plays a leading role in the friction torque of the manipulator.
