摘要
介绍了机翼/外挂系统颤振主动抑制实验的全过程,包括对于模型固有动特性的实验分析、颤振主动抑制系统的调试、以及风洞实验三个阶段。风洞实验在3m×3m低速风洞进行。实验目的是对基于三种不同原理设计的控制律进行验证,并对颤振主动抑制系统进行实验研究。结果表明:所设计的控制律能有效地抑制颤振。经实验验证,控制律的理论计算与实验结果相符。实验系统工作可靠,重复性好。
The whole precess of experiment on active flutter suppression for a wihg/store system is presented in this paper.It involves three steps of the experimental analysis for inherent dynamic characteristic,debugging for active flutter suppression system and wind tunnel experiment.The wind tunnel experiment was conducted in the low speed tunnel of 3m×3m.The puposes of this experiment was to uerify the three control laws based on various principles and also investigate the experimental tecniques on active fitter suppression system.The result of this experiment shows that the flutter could be suppressed effectively by the active control laws designed.It was verified through this experiment that the theoretical computation is well consistent with experimental result and the experimental system is reliable and repeatable.
