传统机械设计中的安全系数概念有较大局限性,可靠性的提出和与安全系数有机联系起来,是机械设计中的一大进步。本文简要介绍了安全系数和可靠性的基本概念以及他们的本质区别,并提出了如何将二者联系起来应用于机械设计的方法。
The concept of safety factor in the traditional mechanical design has more limitations. The reliability improvement and the organic connection with the safety factor make it a great progress in mechanical design. This paper briefly introduces the basic concepts of safety factor and reliability as well as their essential differences, and proposes how to apply the two methods to mechanical design.
