| 摘 要： | 电跳动误差反映了轴类零件表面材料的电磁性质分布差异,加工过程中对此类零件电跳动进行在位测量有助于检验电跳动是否满足加工和机器运行的要求,对控制产品的质量和保证工作性能十分重要。本文提出了一种基于电涡流的电跳动轴类零件在位测量技术,首先介绍了电涡流传感器的工作原理及其电涡流分布规律,然后建立了电跳动检测的有限元分析模型,最后搭建了电跳动在位测量系统,针对空压机转子进行了电跳动在位测量试验,测量结果验证了系统的有效性。

| Abstract: | Electrical runout (ERO) reflects the heterogeneity of electromagnetic characteristics on surface of shaft. On-site measurement can inspect whether the ERO satisfies the processing and the machine operating requirements. It is very important for controlling the product quality and ensuring the working property. An on-site measurement technology of ERO on shaft based on eddy current was presented. Firstly, the working principle of eddy current sensor and the distribution of eddy were introduced. Then, a finite element analytical model for measuring ERO was developed. Finally, an on-site measurement system was set up to measure the ERO of air compressor main shaft. The results verify the validity of measurement system. |
