摘要
威布尔分布是最广泛应用在可靠性工程寿命分析中的一种分布,文章利用威布尔分布参数估计中传统的图估计法借助于Weibull++6.0对MQ—LLS—750型语言学习系统中的星球牌耳机故障参数分析及其可靠性评价,使用Weibull++竞争失效模式分析,阐述了根据它们的耳机样本观测值对其寿命分布进行参数估计的必要性、可靠性和它们的重要意义.
The Weibull distribution is one of the most widely used lifetime distributions in reliability engineering. It is a versatile distribution that can take on the characteristics of other types of distributions, based on the value of the shape parameter, β. This paper provides a brief background on the Weibull distribution for the failure statistics analytical method of the headphone of MQ-LLS-750 language learning system, presents and derives most of the applicable equations, and presents examples calculated by using Weibull++ 6.0 on competing failure modes analysis. It is necessary that the parameters and reliability of lifetime distributions of the headphone were estimated.
