摘要
Weight reduction of the frame type veneer hydraulic press is an important object.The finite element model is made up,importing the 3D model of the frame to the OptiStruct block for meshing and optimization.Static stress analysis is made to the hot press's frame,ANSYS is used to build the frame's finite element model,and then the internal force distribution,displacement and deformation of various parts are obtained under certain working conditions.In order to reduce costs,it is necessary to optimize the previous model and reduce the weight of the frame.Alterable density method is a novel method in topological optimization.OptiStruct is used to make topological optimization of the frame and to obtain the new model.Compared to the previous model,the latter one can guarantee the strength and the rigidity,achieving the purpose of saving materials.
Weight reduction of the frame type veneer hydraulic press is an important object. The finite element model is made up,importing the 3 D model of the frame to the OptiStruct block for meshing and optimization. Static stress analysis is made to the hot press’ s frame,ANSYS is used to build the frame’s finite element model,and then the internal force distribution,displacement and deformation of various parts are obtained under certain working conditions.In order to reduce costs,it is necessary to optimize the previous model and reduce the weight of the frame.Alterable density method is a novel method in topological optimization. OptiStruct is used to make topological optimization of the frame and to obtain the new model.Compared to the previous model, the latter one can guarantee the strength and the rigidity, achieving the purpose of saving materials.
