Topological optimization design of Water-Filled Barrier's structure based on ANSYS Workbench
Aiming at the problems of low material utilization rate and high production cost of the Water-Filled Barrier's structure,a three-dimensional model was established using SolidWorks.The stress and strain of the Water-Filled Barrier in frontal collision of vehicles were simulated using Design Exploration in ANSYS Workbench.Topological optimization design was carried out with the goal of optimizing the Water-Filled Barrier's structure,and a mathematical model with the variable density method as the response constraint was established.The mass and volume of the optimized Water-Filled Barrier's structure were reduced by about 10%compared to the original structure,and the equivalent stress,equivalent elastic strain,and total deformation were reduced by 20%and 47%respectively under the same collision conditions.Therefore,it was reasonable and effective to realized the lightweight design of the Water-Filled Barrier's structure using topology optimization technology,which provided reference for similar optimization experiments.
