摘要
结合电牵引采煤机行走轮的工况特性,给出了失效分布函数及可靠性计算式;介绍了成熟的可靠性分析工具Relex软件,并以MG900/2215-WD系列采煤机行走轮为例,利用Relex的weibull模块对实际失效时间点的数据进行了可靠性分析,得到行走轮的一些重要可靠性数据,为合理检修和寿命预测提供了依据。
Based on the work condition of traveling wheel of electric traction shearer, put forward the failure distribution and reliability formula. Reliability analysis software named Relex was introduced. Take MG900/2215-WD for example, the weibull modual of Relex was used to analyze the actual data and some important data of reliability was obtained, the result provided basis for life prediction and reasonable repair.
