同应力多危险部位轮盘寿命可靠性试验评估方法

Experimental Assessment Method of Life Reliability of a Disk with Multi Same-stress Critical Sites

讨论了轮盘寿命试验评估中基于威布尔分布和对数正态分布的寿命分散系数法。提出两种多危险部位轮盘寿命试验评估的改进分散系数估计法,并以某轮盘概率寿命评估为例说明了改进方法的应用。

Life scatter factor methods for disk probabilistic life assessment based on Weibull and Logarithm normal distributions were discussed first. Then two improved life scatter factor methods were proposed for probabilistic life experimental assessment of a disk with multi critical sites. A numerical example of disk life assessment was given to demonstrate the application of the improved assessment methods.
