摘　　要：电动舵机是直升机等飞行器精确制导的关键部件。随机振动与冲击将直接影响其工作特性。基于多软件联合仿真,提出了一种可用于分析力学环境对舵机工作状态影响的新方法。通过UG建立舵机模型,在应用ADAMS分析舵机正常工作时的力学特性的基础上,采用Patran/Nastran完成了随机振动分析和冲击特性分析,得到了振动、冲击激励对舵机结构和工作特性的影响。并利用振动台进行扫频实验,实验结果表明,所提出的建模、仿真及相关分析方法可有效应用于电动舵机以及其他机电结构的耐力学分析与设计中。Electro-mechanical actuator(EMA) is a key part for helicopter to realize the accurate guidance. Random vibration and impact can affect its working performance directly. Based on multi-software co-simulation, a new method for analyzing the influence of mechanical environment on the working performance of EMA was proposed. The model of EMA was built by UG, and then mechanical property of the EMA interconnecting pieces under work condition was analyzed by ADAMS. After that, Patran and Nastran were used to study the dynamics features including random vibration and impact performance, so as to get influence of mechanical load on the structure and working performance of EMA. Meanwhile, vibration equipment was used to verify the simulation result. The testing result shows that the proposed simulation method can be used for the mechanical analysis and design of EMA, as well as some other electromechanical devices.
