摘　　要：在台架上考核发动机可靠性,采用强化试验方法,其运行规范分为限内、限外两种,前者使发动机所受应力及热负荷不超过使用工况,解决一般性可靠性的问题,后者属超过使用应力,旨在对某些零部件的可靠性作出快速判断;冷热冲击限外试验规范被录用于标准;作者推出十条发动机可靠性评定原则。The authors have divided those various severe operation conditions into two categories.The first category is called as 'limited severe operation program'.The stress level of engine part subjected by limited severe operation shall not exceed that in service.The limited operation programs have been chosen by the draft standards for general engine reliability purpose.The second category is called as 'unlimited severe operation program'.The stress level of engine part subjected by unlimited severe operation shall exceed that in services.For example thermo shock operation is unlimited severe operation program for individual part reliability.The authors have provided then notices for engine reliability assessment.
