Topological Optimization of the Front Beam in Metal Extruders

摘要：

　　According to the outlet shape of the front beam in metal extruders,a topology optimization model of the front beam structure based on the variable density method is established.The effects of the penalty factor on the optimization results are analyzed.By changing the volume fraction,the front beam topology structure with suitable strength and the maximum stiffness is obtained.Based on the topology optimization results and combined with the manufacturing process,the structure of the front beam is redesigned to ensure the manufacturability of the optimized front beam.
