OPTIMIZATION OF THE PREFABRICATED STARTING NOTCH’S PARAMETERS IN THE NUMERICAL SIMULATION MODEL OF FRACTURE SPLITTING CONNECTING ROD

摘要：

In this paper,we present the numerical simulation model of the fracture splitting connecting rod by the FEM software MSC.Marc.For the fracture force which is the key to the process of fracture splitting connecting rod has been greatly influenced by the prefabricated starting notch,the optimization of the parameters of the prefabricated starting notch is very important in some way.We proposes to combine the critical stress intensity factor KIC and JIC to find out the rule of the prefabricated starting notch’s influence on the fracture force in the fracture splitting numerical simulation model.The former can be used to describe and calculate the geometrical factor of the prefabricated starting notch and the later can be used to determine the fracture force of different models with diversified parameters of prefabricated starting notch correspondingly by referencing the numerical simulation results.Since the factors have relationships with the deepness of the prefabricated starting notch,the geometrical factor and the fracture force,the relation curve between the prefabricated starting notch’s parameters and the fracture force of the fracture splitting connecting rod can be established.And this can be used to the optimization of the fracture splitting technology.
