摘要
针对常用的维修性分配方法存在分配给各个产品设计部门的时间并不能完全由各部门控制的不合理现象,以航空装备为研究对象提出了基于时间特性系统维修性分配改进方法.按照将维修时间进行分类分配的思想,提出将装备每个层次产品的维修时间分为共同维修时间和个体维修时间,共同维修时间由系统总体部门或上层产品设计控制,个体维修时间受产品本身或下层单元设计决定.并给出了时间分配模型,对共同维修时间和个体维修时间分别进行分配.最后,结合工程案例利用该方法对维修性指标进行了分配应用,改进方法使得分配到各个产品单元的时间能够真正为各个设计部门所控制,从而真正影响并指导产品的设计,达到维修性分配的目的.
The maintainability allocation work has unreasonable aspect in the engineering application at the present time.According to the traditional method,the allocated time can not be controlled by the design department,and it is hard to achieve the real purpose of maintainability allocation.For this question,the maintainability allocation improved method of the aviation equipment based on the time character was present.The idea is to divide into two parts for the equipment structure,one is common maintenance time,and the other is particular maintenance time.The common maintenance time is controlled by the system overall arrangement department or the higher hierarchy,and the particular time is controlled by the unit or the lower unit design.The maintainability allocation model based on the analysis of the time class to allocate the common time and the particular time severally also was presented.Finally,a case of certain kind of system on aircraft is applied,using the method base on the time character.The improved method allows the allocation time to each product unit can be truly under the control of the various design departments,and thus can really impact and guide product design,to achieve the real purpose of maintainability allocation.
