摘要
针对复杂可修复机械系统的强化试验,提出了可靠性加速系数的计算方法。阐明了可靠性加速系数计算的3个先决条件,即强化试验与使用情况之间的工况可比性、故障模式可比性和故障数据统计规律可比性。还提出了复杂可修复系统在强化试验和使用情况下可靠性等价的条件,并计算出叉车可靠性强化试验的加速系数。
The method for calculating the acceleration factor of reliability intensifying tests of complex maintainable mechanical systems is developed.Three prerequisites in calculation of reliability acceleration factor are introduced,i.e.,the comparabilities of working situa- tions,modes of failures and statistic regularity of failure date between intensifying tests and operating conditions.The equal principle of reliability between intensifying test and operat- ing test of a complex maintainable mechanical system is proposed,and the acceleration fac- tor of the reliability intensifying tests of forktrueks is calculated.
