摘　　要：结合现有试验台的改造和重新设计,从方案设计、动力源选择、轴系部件设计、传感器选用与安装等角度,分析了在高速旋转试验台设计中应考虑的主要问题。提出了新的改进设计方案,实践检验是完全可行的,该设计方案实现了高速旋转条件下固体火箭发动机推力、压力的同时测量,解决了密封问题,试验过程中的振动和噪声减小,并且试验台的运行和维护性能也得到提高。This paper analyzes main problems involved in the design of rocket engine test-bed with high-speed rotation, including the layout design, the choice of drive method, the design of axes and assembly, the choice and installation of sensors. The result shows that the new improved designing layout is practical and realize the coinstantaneous measurement of propulsion and pressure in a high-speed rotation situation. The design solves the hermetic problem, reduces the vibration and noises, improves the application and maintenance performance of the test-bed.
