摘　　要：通过设计具有典型特性的结构,开展其在振动过载综合环境实验的动态响应分布规律研究,分别研究了在不同边界模拟、不同加载角度、不同实验量级等方面的实验结果,获得了典型结构的振动过载综合环境实验响应规律,为复杂结构的振动过载综合环境的响应特性认识以及复杂结构优化设计和振动过载综合环境实验考核奠定基础。A typical structure was designed for the simul.ation of many features of its dynamic response under te vibration and over loading compound environment test. The effects of the different boundaries, the different vibration and over loading compound states and the different test levels of the typical structure are studied in the paper. The results give an experimental basis to investigations of dynamic response of complex structures under vibration and over loading compound environment test. The method can give a foundation to establish the assessment method for compound dynamical environment test.
