Abstract:Aiming at the problems of complex models,insuficientdynamic performance and long solution time in the column structure design of the existing turning and milling compound woodworking machine tools,an optimization design method combining static analysis,modal analysis,corelation analysis andthe response surface of the MOGA algorithm is proposed.Static analysisand modal analysis were carried out on theoriginal column.The results show thatthe original column is prone to resonance,reducing the dynamic performance of the machine tool.A new bionic column structure was designed with reference to the bamboo structure.The design variables were screened through corelation analysis.The total deformation,maximum stress and first-order natural frequency of the column were takenas the optimization objectives to construct the response surface for analysis,and the Pareto optimal solution was outputusing the MOGA genetic algorithm.The optimization results show that the maximum deformation of the column of the turning and milling compound woodworking machine tool has decreased by 5.98% ,the maximum stress has decreased by 9.06% ,the first-order natural frequency has increased by 2.64% ,and both the static and dynamic performances of the turning and milling compound woodworking machine tool have been improved. KeyWords:turning and miling compound machine tool column;response surface method;parameter correlation analysis;multi-objective optimization
