中文百科
失效率![]() ![]() ![]() 失效率(英语:Failure rate)是一个工程系统或零件失效的频率,单位通常会用每小时的失效次数,一般会用希腊字母λ表示,是可靠度工程中的重要参数。 系统的失效率一般会随着时间及系统的生命周期而改变。例如车辆在第五年时的失效率会比第一年要高很多倍,一般新车是不会需要换排气管、检修煞车,也不会有重大传动系统的问题。 实务上,一般会使用平均故障间隔(MTBF, 1/λ)而不使用失效率。若是失效率假设是定值的话,此作法是有效的(定值失效率的假设一般常用在复杂组件/糸统,军事或航天的一些可靠度标准中的也接受此假设),不过只有在浴缸曲线中平坦的部份(这也称为「可用生命期」)才符合失效率是定值的情形,因此不适合将平均故障间隔外插去预估组件的生命期,因为当时会碰到浴缸曲线的损耗阶段,失效率会大幅提高,生命期会较依失效率推算的时间要少。
英语百科
Failure rate 失效率![]() ![]() Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is often denoted by the Greek letter λ (lambda) and is highly used in reliability engineering. The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system. For example, an automobile's failure rate in its fifth year of service may be many times greater than its failure rate during its first year of service. One does not expect to replace an exhaust pipe, overhaul the brakes, or have major transmission problems in a new vehicle. |
