车辆机械部件验证的一个重要问题是通过试验对高里程的可靠性进行评估。由于测试应尽可能短，并且对于遭受磨损或裂纹扩展等退化机制的零件，使用退化测量（例如质量损失或裂纹长度）来估计可靠性是合适的。在这项研究中，我们提出了一些统计方法来应对这一问题，并提出了一种方法来比较这些模型。可以使用不同类型的数据;在本文中，我们只考虑每个部分都有一个测量值的情况。仅研究线性降解。
An important issue in the validation of mechanical parts for vehicles is reliability assessment for high mileages, by means of tests. Since the tests should be as short as possible, and for parts subjected to degradation mechanism, such as wear or crack propagation, it would be appropriate using degradation measurements (such as mass loss or crack length) in order to estimate reliability. In this study, we present some statistical approaches responding to this concern and propose a method to compare theses models. Different types of data can be available; in this paper, we only consider the case in which one measure is available for each part. Only linear degradation is studied.
