Design of Virtual loading System for Aerodynamic Loader

摘要:

飞行器在飞行过程中,舵机将承受到空气动力的力矩载荷,气动负载虚拟负载模拟器是用于模拟空气力矩载荷变化规律的地面半实验设备；针对在地面试验过程中,传统负载模拟器与承载系统因机械结构耦合而产生的“多余力矩”问题,以磁粉离合器和力矩传感器为核心,构建虚拟负载模拟器,利用系统输出转矩的大小和方向分别只与励磁电流的大小和速度滑差的方向有关的特性,较彻底地解决“多余力矩”的问题,提高力矩加载试验设备的性能,从而进一步提高飞行器虚拟试验的水平。

Abstract:

During the aircraft’s flight, steering gear may sustain aerodynamic torque loader. Motor drive load simulator is the ground hardware-in-the–loop equipment which is used for simulating aerodynamic torque loader’s change rule. For the ground test procedure, the problem of surplus torque arises because the mechanical structure’s coupling between the traditional load simulator and the bearing system. Based on the magnetic particle clutch and torque sensor, we can structure virtual load simulator,by using the characteristic of torque’s size and direction only related to speed slip’s direction. We can settle the surplus torque finally. It improves torque loading test equipment’s performance, and results in a more highly level of aircraft’s virtual test.
