【摘要】 在分析飞行器飞行过程中舵面受力情况的基础上,提出了一种新型舵机加载装置,在舵面持续运动的情况下能够模拟和舵面运动方向相反的空气阻力矩,弥补了弹簧扭杆加载模拟空气阻力矩仅向一个方向的不足;能够模拟舵面运动过程当中不断变化的摩擦力矩,弥补了以往用常值替代摩擦力矩的不足;能够模拟舵面运动过程中的惯性力矩,解决了惯性力矩较难模拟的问题,为舵机的性能试验提供了新的检测设备。实验结果证明了这种新型加载装置的设计方案是可行的。更多还原

【Abstract】 A new actuator loading device is proposed on the basis of analyzing the force on the rudder under flying condition.Compared with the traditional flexible lever loading method,the device can present a more similar load of the real atmosphere moment to the flying rudder.It can also simulate any relation with functions between rudder deflexion and atmosphere moment.The simulations demonstrate that it can offer a better means to the actuator performance test.更多还原
