考虑Gauss移动热源瞬态效应的传热结构拓扑优化
Topology Optimization of Heat Transfer Structures Under Gaussian Moving Heat Source Transient Effects
摘要
Abstract
For the structural heat transfer problem with heat sources moving with time,the Gaussian moving heat sources were considered for transient heat transfer topology optimization design.The design objectives are to minimize the total heat dissipation of the structure over the entire time history and to minimize the maximum temperature in particular regions,with the volume fraction as the constraint.Sensitivity information for the ob-jectives and constraints was derived with the adjoint variable method,and design variables were updated with the moving asymptote method.The effects of different Gaussian heat source paths and speeds on the topology optimization results were studied.The numerical results indicate that,the transient topology structure exhibits pronounced time-varying characteristics compared to the steady-state results.Moreover,the optimal heat dissi-pation configuration depends on multiple factors,including the heating time,the path and the speed of the moving heat source.关键词
