| 摘 要： | 研究了随机载荷作用次数对齿轮可靠性的影响.通过引入条件可靠度,在不作失效独立假设的前提下,运用应力-强度干涉模型建立了具有多种失效模式的齿轮可靠度计算模型.根据随机载荷作用的统计学意义,运用顺序统计量理论建立了随机载荷多次作用时的齿轮可靠性模型,并研究了齿轮可靠度随载荷作用次数的变化规律.研究表明,即使在强度不退化的情况下,齿轮的可靠度也随着随机载荷作用次数的增加在逐渐降低.

| Abstract: | The effect of frequency of loading actions on the reliability of a gear is studied.With the conditional reliability introduced in and without the assumption that there is independent failure mode of gear,a reliability calculation model of gear with multiple failure modes is developed using the stress-strength interference model.According to the statistical meaning of random loading actions,the reliability model of a gear under frequent random loading actions is developed with the theory of order statistic.A... |
