| Abstract: |
| 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. |
