摘要
借鉴可靠性分配模型建立方法,建立了机械装备测试性分配模型;并将测试性分配问题转化为求分配因子,提出了基于投影寻踪的子系统重要度评价方法,依据子系统重要度,获得各子系统分配因子并最终分配测试性指标;以柴油机为例进行了测试性分配,结果证实论文提出的分配方法合理可行.
Reliability of distribution modeling method,mechanical equipment testability allocation model was firstly established.Then translate the testability allocation problem into seeking distribution factor;Pojection pursuit method was proposed to evaluate subsystem importance,And based on subsystem importance acquired the distribution factor of each subsystem,the subsystem distribution factor is obtained and the test index is finally assigned.Finally,a diesel engine allocation example was given as an example,the allocation result dedicate the testability allocation method proposed in this paper is reasonable.
