Abstract
In order to increase value of the first natural vibration frequency, as well as gain more economic benefits by lightening the weight of combined frame of high speed hydraulic press, on the basis of proposing concept of generalized finite element module, topological optimization of prestressed combined frame was carried out with limited computing resource by means of combination of cut boundary interpolation of submodeling with generalized finite element modules. Process and results convinced that the approach was effective and highly efficient at large machine design.
