- W2350679682 abstract "A design strategy for optimizing the design of machine tool bed structure is suggested by combing size optimization based on the approximate model with the topology optimization technology.First,by taking the rigidity and fundamental frequency of the machine tool bed structure as the design targets,by using the distance between lateral partitions in the machine tool bed,thickness and distance between leveling iron blocks as the design variables,the sample points of the design variables required by the test were generated by using the compromise design method.And response of generated sampling points was obtained by using finite element analysis,establishing the secondorder response surface of approximation model by using the least square method.The multiobjective optimization model was established by adopting the compromise design method,and the optimal result was obtained by using genetic algorithms.Based on this,topology optimization on the machine bed structure was carried out by using the density method.The result of a typical example shows that the weight of the bed is reduced by 4.45% while the rigidity is increased by 5.98% after optimization." @default.
