Abstract
An effective parameterization method is proposed to optimize transition arc's shape between blot head and blot bar for minimum stress concentration. This method adopts super circular curve equation to describe transition arc’s shape, then selecting equation’s parameters as the design variables. Thus it becomes very easy to describe and obtain optimal transition arc's shape just making use of the optimization module provided in a commercial finite element package due to the less number of design variables. Finally, an example of hexagonal bolt M64 is presented and discussed to demonstrate the accuracy and the practical of the proposed shape optimization method.
