| 摘 要： | 本文讨论了实验/分析模态双协调综合实现中实验子结构转角自由度和集中力矩柔度的测量问题。首次提出基于有限元理论的双无加载概念,并通过仿真计算说明其在转角自由度测量的应用价值.最后以一汽车底架模型为实例,经过分析综合和实验(/分析)综合,实践了本文的主题.

| Abstract: | The problem of measuring rotational DOF and pure moment flexibility for experimental substructures in combined experimental/analytical dual-compatible mode synthesis is discussed in this paper. Based on the FE theory, a new concept called no-inertia-nor-constraint is put forword. It's application in measuring rotational DOF is explained through numerical simulation. In the end combined experimental/analytical dual-compatible mode synthesis is practiced by taking a chasis model as an example. |
