- W2354514725 abstract "Topology optimization design of planar continuum structure with randomness of both geometry and physical parameters under structural foundamental frequency constraint was studied.Mathematical model of topology optimization design of random structure was established,in which the mean of structural weight was taken as minimization objective function,the structural shape topology information was taken as design variables,and the probabilistic reliability index of structural foundamental frequency was taken as constraint conditon.The computational expressions of the mean value and mean variance of the structural dynamic response were presented by means of the algebric synthesized method.Evolutionary structural optimization method was used in optimization.Through two examples,the rationality and feasibility of the optimization model and solving method were validated." @default.
