摘要:

针对运载火箭推力矢量伺服控制系统的多自由度特性问题,提出一种新的负载模拟结构并建立了数学模型。通过仿真分析了主要机械设计参数对系统动态特性的影响。建立原理性实验系统,通过扫频实验验证了伺服机构的多自由度特性。仿真和实验证明了此种负载模拟原理的可行性,从而为优化推力矢量伺服机构的设计参数以及研制大型运载火箭伺服系统的负载模拟系统提供设计依据。

Abstract:

Aiming at load simulating problem of the thrust vector control (TVC) system in launch vehi- cles, a new load simulator structure and its mathematical model are presented. The influence of main pa- rameters on system爷s dynamic performance is analyzed by simulation. Building a prototype experiment system, multiple DOF load property is showed in a sweep frequency test. Simulation and experiment veri- fy the feasibility of this load simulator structure, which lay a foundation for optimizing design parameters of the thrust vector servo mechanism and developing load simulators of heavy launch vehicles爷servo sys- tems.

Key words: experimental technology of aerocraft, thrust vector, multiple-DOF, dynamic characteristic, load simulation
