Fractured Reasons Analysis and Structure Optimization of a Light Truck Steering Bracket

In this paper, combination of a light truck’s market issues, use HyperWorks software to do the finite element analysis of the fractured bracket, and improve the structure by topology optimization, optimized bracket compared with fractured bracket, obviously reduction of the maximum stress, and lighten the weight. Experimental verification of the final optimized stands by the reliability, indicating that the structure of CAE-based analysis and topology optimization, can provide the means for product failure analysis, find the optimal solution for product design, and is a also very important way for vehicle lightweight.
