某驾驶员操纵装置非线性问题解决方案

Solution to Nonlinear Problem on Pilot's Control Device

某型飞行模拟器在进行驾驶员操纵装置静态特性测试过程中,发现其纵向、横向的杆力——杆位移曲线呈非线性变化,与理论的线性梯度曲线不符。本文通过LMS Virtual.Lab软件对相关对象进行了仿真分析,找到了出现非线性问题的原因,提出了可行性的解决方案,并对其方案进行了仿真验证。

During the static test of the pilot＇s control device of a flight simulator for one type of aircraft, it is found that the longitudinal and lateral stick force, i.e. the stick displacement curve is nonlinear, which is not in conformity with the theoretical linear gradient curve. This paper carries out simulation analyses for relevant objects through software LMS Virtual.Lab, thus finding out the cause of the nonlinear problem and providing feasible solution, meanwhile, the new solution is verified by simulation.
