摘　　要：根据"菲涅耳"光学助降装置发射光束的稳定性设计要求,提出采用一种二自由度并联驱动摇摆台来检验该装置随动系统的稳定性能。采用解析法建立了该试验台的运动方程,算例仿真分析结果表明:通过驱动主运动支链杆长的移动,可以实现既定规律下运动平台的横摇和纵摇运动,完全满足"菲涅耳"光学助降装置的性能测试要求。the parallel forward. Th According to the stability requirement of the emissive beam in fresnel lens optical landing aid system, tilter with two degrees of freedom which can try out stable performance of the servo in the system is put e kinetic equation of test platform is constructed based on the analytical method, simulation result indicates that the parallel test tilter can realize the rolling and pitching motion which follows the ordering principles by driving the motion of the piston rod in the main branching chain, and satisfy the property testing of the Fresnel lens optical landing aid system.
