Optimization of Design Parameters of Circular Burring

摘要

The paper presents an example of an automotive handle bracket. The design parameters of burring include fillet radius R, burring diameter D and burring height H, which are all analyzed in this paper. The objective function is thinning rate of parts. By using quadratic regression, a mathematical model between objective function and design parameters can be established, which can be guidance while selecting design parameters of burring.
