Research On Finite Element Simulation Of Steering Kunckle Forging Process

With the high development of the automobile industry, automobile performance advances continually. New forging processes, material and energy saving processes are very important to the production of new type of auto parts.Steering knuckle is one of the most important car key parts and a safety part. It supports the body weight, transfers steering moment and endures braking moment of front-wheel. The requirement of its mechanical characteristics and contour structure is so strict that it is very hard to produce. It is urgent need to solve the problem that how it can be produced efficiently and economically.In this paper, the forging process of steering knuckle is analysed, get the blank drawing of steering knuckle, select equipment, and get the forging process of steering knuckle. Design the die of steering knuckle forging process, the main parameters of pre-forging process and final forging is obtained. The three-dimensional finite element software DEF0RM-3D is used to perform the hot die forging of the car steering knuckle. The forming process of the performing, preforging and finish-forging for the steering knuckle is analysed. The material deformation laws and load-stroke curve are predicted. The distribution of the stress and strain in workpiece is obtained.New forging process of steering knuckle is proposed. In this new forging process, the pre-forging process is improved to new flashless die forging process. Analyse the flashless die forging process of steering knuckle. Numerical simulation of new forging process is analysed. Effect of the width of flashless die forging on forging process is studied. The main parameter of flashless die forging process is obtained.
