Abstract：

The initial drawing coefficient is an important parameter for multi-stage drawing process and product quality of deep cylindrical parts, which is mainly selected from experiences and repeated trials in engineering application. Therefore, it is urgent to select the initial drawing coefficient quickly and accurately for deep cylindrical parts. Therefore, a new method determining the initial drawing coefficient of deep cylindrical parts was put forward to get the maximum thickness reduction ratio by combining finite element method with 0.618 optimization method. A deep cylindrical experiment was conducted to test this new method. The result shows that the predictive accuracy of the new method is coincident with that gained by the empirical method. At the same time, the maximum thickness reduction ratio is controlled by 11% for steel DC01 or similar materials during the multistage deep drawing process, and the following process of deep drawing can be carried out successfully.
