摘要

摘要: 对设计的负载模拟器采用复数矢量法与虚位移原理建立其机构动力学与多余力矩数学模型.在此基础上针对传统遗传算法优化解不一致的情况,提出了基于参数灵敏度分层的遗传算法优化方法并对设计中各参数进行了优化.根据优化结果设计虚拟样机,并利用ADAMS进行多种加载信号的仿真,结果表明样机各项指标均达到设计要求,依此设计出一套可同时进行环境试验与多种负载加载的反操作负载模拟器.

Abstract: The dynamics and extraneous torques models of an anti-load simulator were built according to the complex vector and virtual displacement principles respectively. To avoid the problem that the solution is not consistent when the traditional genetic algorithm (GA) is used in the parameters optimization, the hierarchical optimization of GA based on the parametric sensitivity was applied to optimize the design parameters of the mechanism of the anti-load simulator. Then a virtual prototype was designed according to the optimizing results, and testified by the simulation in ADAMS with various loads applied. The results show that the prototype is able to withstand the complex environment conditions and loads in simulating tests. Finally, the real anti-load simulator was established with functions working in environment tests and under various loads.
