凸轮磨损的研究综述与思考

Overview and Consideration on Cam Wear

通过对国内外研究现状的调查总结,分析了目前凸轮磨损工程及仿真实验的研究现状,概述了凸轮磨损的预防措施,归纳了失效凸轮常用修复方法,最后对凸轮磨损问题研究在利用载荷谱进行实验研究、利用阶段磨损率进行仿真研究、利用在线自动修复实现防修结合等方面提出了有益的建议。

Based on the investigation and summary of the research research status about cam wear at home and abroad,the research status on the engineering experiment and simulation experiment of cam wear are analyzed.Precaution measure against cam wear are summarized and common repairment methods of failure cam are present.Finally,some helpful suggestions against cam wear,such as experimental study with load spectra,simulation study with the different wear rate at different wear phase,on-line auto-repairing for the combination of precaution and repairment are proposed.
