摘要:

针对飞机舵机负载的电动加载系统中多余力矩的来源和机理问题,建立电动加载系统的功能模型。采用数值仿真和蒙特卡罗方法分析多余力矩的来源及其主要影响因素;通过单参数和多参数情况下的影响分析和验证系统外部输入和内部扰动对多余力矩的影响机理和影响程度。结果表明:多余力矩主要受加载指令频率、传感器信号偏置、加载电机参数等因素的影响,尤其是加载指令频率对多余力矩的影响最为显著,加载指令频率每变化10%,引起的多余力矩变化比其他因素至少多出124倍。

Abstract:

To address the issues of sources and mechanisms of parasitic torque in electric loading systems for aircraft actuator loads, a functional model of the electric loading system was established. Numerical simulations and Monte Carlo methods were employed to analyze the sources of parasitic torque and its primary influencing factors. The influence mechanisms and degrees of the system's external inputs and internal disturbances on parasitic torque were analyzed and validated through single-parameter and multi-parameter analyses. The results indicate that parasitic torque is predominantly influenced by factors such as loading command frequency, sensor signal bias, and loading motor parameters. In particular, the loading command frequency has the most significant effect on parasitic torque; a 10% change in loading command frequency causes a variation in parasitic torque at least 124 times greater than that caused by other factors.

Key words: electric loading system, parasitic torque, numerical simulation, frequency domain analysis, loading command frequency
