摘要
针对实时子结构试验加载方式复杂,控制精度低的问题,本文提出通过AMD装置进行加载实现数值子结构与试验子结构的界面力相容条件,降低试验造价,简化加载方式。通过力反馈进行高精度控制,提高试验的针对性和研究效率。分析与模拟的结果都表明,对于所提出的基于AMD力控制的振动台子结构试验方法具有可行性与有效性。
Aiming at the problem of complex loading mode and low control precision in real time substructure test, this paper puts forward the interface force compatibility condition of numerical substructure and experimental substructure by AMD device, which can reduce the test cost and simplify the loading mode. High precision control is carried out by force feedback to improve the pertinence and research efficiency of the experiment. The results of analysis and simulation show that the proposed method of substructure test based on AMD force control is feasible and effective.
