耐久性及其在装备研制中的应用

机械产品在武器装备中占有较大的比例，机械产品的故障，有很多是由于疲劳、磨损、腐蚀、老化等渐变性的耗损过程造成的，寿命是机械产品可靠性中的重要问题。耐久性的提出为解决机械产品与寿命有关的问题提供了方法和工具。通过探讨耐久性的定义、极限状态、耐久性参数、耐久性分配与预计等有关耐久性的基本问题，给出了耐久性分配与预计的工程实例。

Durability and Its Application in the Development of Equipment

Mechanical products occupy great proportion in weaponry equipment, the faults of which often resulted from some wearing out processes such as fatigue, abrasion, erosion and aging. Service life is one of the most important problems in mechanical reliability. Durability is set forth to solve the problem associated with service life of mechanical product. In this paper probe the definition of durability. the limiting conditions, the parameters of durability, the allocation and prediction of durability and provide engineering examples of the application of durability allocation and prediction.
