维修包括维护与修理。维修费用在很多产品(特别是武器)的整个寿命周期总费用中占相当大的比重,它在很大程度上决定于产品的固有维修性。因此在任务书或合同中,对产品要有维修性要求。承制方要制订维修性大纲,规定在产品研制、生产、使用的各个阶段所必须进行的定性或定量的维修性工作项目。其中特别要抓好维修性设计;产品要有良好的可达性,高互换性,标准化程度高,保证操作及维修安全,防止人为差错。产品要具有高可检测性,并按人-机工程进行设计,要降低维修项目的数量及维修频率、维修费用。常用件(紧固件、润滑装置、轴承、密封件、接插件)的维修性是维修性设计的重点。还要展开维修性预测、维修性分配、维修性的定性及定量鉴定、维修性验证等工作。
Maintenance includes maintenance and repair. Maintenance costs represent a significant portion of the total cost of ownership for many products, particularly weapons, and are largely determined by the intrinsic maintainability of the product. Therefore, in the mission statement or contract, the product requires maintenance. The undertaking side shall formulate the maintenance outline, stipulating the qualitative or quantitative maintenance work items that must be carried out in all stages of product development, production and use. In particular, we should pay attention to the maintenance of design; products should have good accessibility, high interchangeability, a high degree of standardization to ensure safe operation and maintenance, to prevent human error. Products to be highly detectable, and by man-machine engineering design, to reduce the number of maintenance projects and maintenance frequency, maintenance costs. Maintainability of commonly used parts (fasteners, lubricators, bearings, seals, connectors) is the focus of maintainability design. But also to carry out the maintenance of predictions, maintenance of the distribution, maintenance of qualitative and quantitative identification, maintenance of verification and other work.
