Abstract：

Topology optimization is an important method in the lightweight design of cold heading machine bed. For the issues of different optimized indexes and insufficient optimization spaces due to premature convergence in topology optimization of cold heading machine bed, a method of iterative optimization was put forward by alternately changing the volume and strain energy of cold heading machine bed into objective function and constraint. Furthermore, the beds weight and overall rigidness were approximate to an optimal value by updating methods according to the optimization results. Therefore, the thought of iterative optimization was described, the iterative optimization model with the optimized indexes of the beds volume and strain energy were constructed, the flow of iterative optimization was planned in detail, and the termination condition of optimization was established. Finally, for a type of cold heading machine bed, the process of its iterative optimization was realized by Abaqus 6.12. The result shows that the above method has play an important role in reducing the beds weight, enhancing the overall rigidness and improving some mechanical properties.
