城市公交客车可靠性试验强化系数分析计算方法研究

Study on Calculation of Enhancement Coefficient in Reliability Test of City Bus

为了对城市公交客车可靠性强化试验结果进行有效、合理地评价以及更好地对产品设计提出改进意见,研究了可靠性试验强化系数的计算方法。进行了用户路线确定,对用户载荷谱获取与统计,完成损伤数据概率分布检验和目标单位里程损伤获取。结合强化试验数据,最终计算获得可靠性的强化系数结果。最终形成了一套基于实测数据的城市公交客车可靠性试验的强化系数分析计算方法和流程,有利于产品可靠性水平的提升。

In order to effectively and reasonably evaluate the enhancedreliability test results of city bus and put forward improvement suggestions for product design,the calculation method of enhancedreliability test coefficient is studied.The customerroute is surveyed and determined,the customer road load spectrum is obtained and load spectrumstatistics is finished.And the probability distribution test of damage data and the damage acquisition of target unit mileage are completed.With the enhanced test data,the enhancement coefficient of reliability is finally calculated.Finally,a set of calculation method and process of enhancement coefficient of bus reliability test based on measured data are formed,which is conducive to the improvement of product reliability.
