摘要
阐述环境振动试验面临的新情况及其发生的背景。分析环境振动实验当前存在的问题,对柔性夹具、试件动力学边界条件的工程实现、振动台模态参数识别、结构的模态转换等新进展做简要介绍。对我国环境振动试验的近期发展进行简短的展望。
The new situation that faces the environment vibration experiment (EVE) and the background of this change are expounded. The existing problems of EVE are also analyzed, the new developments, such as flexible clamp, simulation of the dynamic boundary conditions of a specimen, modal parameter identification by vibration shaker, modal transformation of structure are introduced briefly. In the meanwhile, a simple prospect about recent developments of EVE in China is carried out as well.
