【Abstract】 By correlating the dynamic stress calculation and the fatigue life analysis of an element on a blocking mechanism, and from the point of view of working life, a simple optimization design method for an element on a blocking mechanism is put forward. This makes it possible to design quantitatively the local position dimensions of localities having stress concentration in the element. Application of the method on a design shows that the results are reliable, and that the method can furnish guidance to practical engineering designs.更多还原
