摘　　要：主动杆俯仰与横滚操纵解耦技术是现代先进战斗机的一项关键技术,主动杆俯仰与横滚操纵隔离机构的机械结构设计尤为重要。针对如何通过机构隔离主动杆俯仰与横滚两方向的操纵,实现操纵解耦问题,首先借鉴两自由度陀螺仪的框架结构原理,设计了俯仰与横滚操纵的隔离机构,并利用CATIA建立了隔离机构的三维实体模型,然后使用有限元分析软件ANSYSWorkbench对隔离机构进行了模态、随机振动以及静力学等力学特性仿真分析,结果表明设计的隔离机构满足强度和稳定性要求。为主动杆俯仰与横滚操纵的隔离问题提供了解决方案,为进一步设计优化及试验研究提供了参考。The decoupling technology of pitch and roll control of Active Side-Stick(ASS)is a key technology of modern advanced fighters,so the mechanical structure design of pitch and roll control isolation mechanism of ASS is particularly important.In order to isolate the control of pitch direction and roll direction of ASS through the mechanism,and to solve the operation decoupling problem,the isolation mechanism for pitch and roll control is designed by referring to the frame structure working principle of two degrees of freedom gyroscope,and the 3D model of the isolation mechanism is established using CATIA.Then modal analysis,random vibration analysis and static analysis of the isolation mechanism are carried out by using ANSYS Workbench.The results of simulation analysis show that the rigidity and stability of the designed mechanism are verified to satisfy the requirements.The separation of pitch and roll control problem of ASS is solved,and the work in this paper provides a reference for further design optimization and experimental research.
