摘要
主要介绍了“机械强度有限寿命设计技术”，它的特点是在产品设计图纸上出现了使用寿命系数，即用产品的可靠工作时间指数代替了经验设计中的保险系数来保证设备的可靠性。同时，通过新旧设计方法的类比，进一步说明提高机械产品的研制水平、掌握现代设计技术的必要性。
The technology of limited life-time mechanical strength design is briefly introduce in this paper. Its feature is to use a life -time coefficient in the product design. That is to say, the coefficient of dependable working time replacing the safety coefficient of empirical design will be used to ensure the dependability of equipment. It is essential to master and apply the modem designing technology so as to enhance the development level of mechanical products.
