摘要

以获得高速动静压混合气体轴承转子系统所能达到的最高转速为实验目的,通过三维谱图,时间响应图,Bode图和轴心轨迹图分析了该系统的动力学特性。实验表明,动静压混合气体轴承支撑的转子(重量为15.19千克)在转速达到42000转/分出现低频涡动现象,进而为旋转冲压发动机轴承支撑系统设计提供实验依据。

Abstract

An experiment for the high speed hybrid gas bearing was presented in this paper to acquire the highest rotating speed of the system. The dynamic characteristics were analyzed by employing the three dimensions spectrum, response time diagram, bode diagram and axis center locus diagram. The results indicated that the low frequency whirl phenomenon of the rotor (weights: 15.19 kg) which supported by the hybrid gas bearings can be observed at the rotating speed of 42700rpm. This supplied the experimental supervision for the bearing support system design of rotating ramjet.
