摘要

Taking the lower arm of DK7725 WEDM Taper Machine as the research object, this paper uses the ANSYS Workbench collaborative simulation environment to analyze equivalent stress and deformation of the lower arm in the different working conditions, find the weak part of Lower Arm, analyze static structure of the lower arm, and improve lightweight design. According to the characteristics of Taper Machine overall structure and optimization variables, using the Design of Experiments (DOE) method, this paper combines the response surface method (RS), goal driven optimization method (GDO) with multi objective genetic algorithm optimization method (MOGA) with the candidate schemes, extractes candidates from the calculation program, insert the candidates as the design points into the whole optimization calculation. By controlling parameter allowable error, this experiments obtains the best optimal solution. The results show that if the mass of the lower arm is decreased 13.28%, the lower arm has stable dynamic performance, and get good optimization effect.
