| 摘 要： | 为了研究高温超导磁悬浮轴承样机的动态旋转特性,介绍了由振动分析仪、转速计和位移传感器组成的动态测试平台。该测试平台不仅可以测试高温超导磁悬浮轴承的共振频率、刚度和阻尼系数等基本动态参数,而且可以实时测试旋转轴承的转速和振动偏移等运行参数。通过脉冲激励实验和自由衰减实验证实测试实验数据真实可靠。该平台的搭建将为本小组在轴对称式高温超导磁悬浮技术(轴承、飞轮等)的应用研究和开发奠定基础。

| Abstract: | To investigate the dynamic rotational behaviors of high temperature superconducting magnetic bearings(SMBs),a dynamic test platform composed of vibration analyzer,tachometer and displacement sensor was presented in the paper.The platform can not only evaluate the basic dynamic parameters,i.e.,resonance frequency,stiffness and damping coefficient,but also test the running parameters of speed and vibration offset of SMB in real time.Moreover,the reliability of the experimental data was verified by the pulse e... |
