故障(失效)及其分类故障(失效)在可靠性工程中是一个极为重要的概念。在工程中要提高产品可靠性,就要与故障做斗争。要评价产品可靠性,就要明确故障的定义及其分类。故障是指产品不能执行规定功能的状态,通常指功能故障。失效是指产品丧失完成规定功能的能力的事件。故障模式是指故障的表现形式,如短路、开路、断裂、过度耗损、漏油等。故障机理是指引起故
Failure (failure) and its classification Fault (failure) is a very important concept in reliability engineering. In the project to improve product reliability, we must fight the failure. To evaluate product reliability, it is necessary to define the definition of failure and its classification. Failure refers to the state of the product can not perform the specified functions, usually refers to the functional failure. Failure refers to the loss of the ability to perform prescribed functions. Failure mode is the manifestation of failure, such as short circuit, open circuit, fracture, excessive wear and tear, oil spills. Failure mechanism is caused by the reason
