基于威布尔分布的起重机械可靠性寿命分析

摘要

Through comparison and analysis,the least square method is used to estimate Weibull distribution parame-ters,and the service life model for crane built to analyze the fault rule of the hoisting machinery.The distribution model is adopted for analysis of the reliable service life index.%通过比较分析使用最小二乘法估计威布尔分布参数的方法，建立起重机械寿命模型的方法，分析起重机械故障规律，利用分布模型分析其可靠性寿命指标。
