机械设计中安全系数与可靠性的研究

Research for safety factor and reliability in machine design

从材料强度的离散性和相当载荷具有统计性的事实出发 ,在机械设计中 ,计算其安全系数的同时 ,应计算其可靠性。

Due to the fact that the irregular of the strength of metal and the statistical of the real load.It must be calculate the safety factor together with the reliability in machine design.
