摘要
针对煤矿带式输送机驱动电机难以准确进行可靠性研究的问题,基于故障数据建立三参数威布尔分布模型,结合最小二乘法和相关系数法对模型求解,最后得到带式输送机驱动电机的预防性维护周期、概率密度函数、可靠度函数,并进行可靠性分析。实例表明,该方法能够基于带式输送机驱动电机失效数据进行可靠性分析,可用于指导现场开展设备维护工作。
Aiming at the problem that it is difficult to accurately study the reliability of coal mine belt conveyor drive motor,a three-parameter Weibull distribution model was established based on the fault data,and the model was solved by the least square method and correlation coefficient method. Finally,obtained the prevention maintenance period,a probability density function,a reliability function of the belt conveyor drive motor,and carried out reliability analysis. The example shows that the method can be used for reliability analysis based on the belt motor drive motor failure data,which can be used to guide the on-site equipment maintenance work.
