CVT金属带钢环疲劳试验数据可靠性分析

Analysis reliability test data of the steel ring of metal v-belt

在CVT金属带钢环疲劳试验数据的基础上,通过作图法和数值分析法检验,确定了钢环寿命符合对数正态分布;采用解析法和作图法估计了分布函数参数,并得到了钢环的可靠寿命表达式。

Based on the fatigue test data of the steel ring of Metal V-belt,It confirms that the life distribution of steel ring obeys the lognormal distribution through the Graphic and the Numerical Analyses. Both the analysis and the construction are used to estimate the distributing function parameters. And it is obtained that the reliable life expressions of the steel ring.
