摘　　要：针对飞机舵机电液伺服系统在抑制多余力干扰时,缓冲装置无法实现变刚度连续加载的问题,采用在系统结构中设置橡胶-金属缓冲弹簧的结构补偿方法。首先,设计橡胶-金属缓冲弹簧结构,利用ANSYS仿真软件构建有限元模型并对其进行性能分析。通过构建飞机舵机电液伺服系统各元件数学模型,从而得到系统整体数学模型。最后,利用MATLAB仿真软件验证该方法的可行性和有效性。研究结果表明,橡胶-金属缓冲弹簧能够达到技术指标要求,改善系统稳定特性,具有较高的工程实践价值。Aiming at the problem that the buffering device can′t realize the continuous loading of variable stiffness when the electro-hydraulic servo system of aircraft steering gear can restrain the interference of extra torque,the structural compensation method of setting rubber-metal buffering spring in the system structure is adopted.Firstly,the rubber-metal buffer spring structure is designed,and the finite element model is constructed with ANSYS simulation software and its performance is analyzed.Then,by constructing the mathematical model of each component of the electro-hydraulic servo system of the aircraft steering gear,the overall mathematical model of the system is obtained.Finally,MATLAB simulation software is used to verify the feasibility and effectiveness of the method.The results show that the rubber-metal buffer spring can meet the technical requirements and improve the stability of the system.
