Flexible test run test device for solid rocket engine in vibration excitation environment

The invention discloses a solid rocket engine flexible test run test device in a vibration excitation environment, and belongs to the technical field of machinery. Comprising a test bed mechanism fixed by a bearing pier, a test bed frame mechanism mounted above the test bed mechanism in a front-back rolling manner, a rapid thrust balance mechanism positioned in front of the test bed frame mechanism and mounted on the test bed mechanism, a vibration excitation mechanism mounted on the test bed mechanism, and horizontal suspension mechanisms fixed on two sides of the test bed mechanism. The free state of a flight test is simulated to a certain extent by releasing the degree of freedom of the engine in the working process, and external excitation is loaded in the engine ignition process. 一种振动激励环境下固体火箭发动机柔性试车试验装置，属于机械技术领域，包括：承力墩固定的试车台机构、可前后滚动的安装在试车台机构上方的试车架机构、定位在试车架机构前方且安装在试车台机构上的快速推力平衡机构、安装在试车台机构上的激振机构以及固定在试车台机构两侧的水平悬吊机构。本发明通过释放发动机工作过程中的自由度，一定程度上模拟飞行试验的自由状态，实现在发动机点火过程中加载外部激励。
