基于变密度法的万向支撑下支座拓扑结构优化
Structural Topology Optimization of the Support Under Gimbaled Support Based on the Variable Density Method
摘要
Abstract
Woodchip screening device is one of the key components of woodchip vibrating screen which is an important equipment in the front-end industrial chain of papermaking industry.Taking the lower support of its universal support structure as the object of research,aim to reduce the quality of the lower support and improve its stability,and optimize the structure and shape of the lower support.A 3D model of the lower support is created in 3D software;the lower bearing model is imported into the finite element software HyperWorks for static analysis under the ultimate load condition,and the deformation cloud and stress cloud of the lower bearing are obtained;based on the results of the static analysis,topology optimization of the lower support is carried out using the Optimization module of HyperWorks,so as to optimize its structural topology optimization and shape.The results of stress,deformation and modal analysis before and after topology optimization are also compared and analyzed.The results of stress,deformation and modal analysis before and after topology optimization are also compared and analyzed.The results showed that the mass of the lower bearing is reduced by 41.15%and the displacement is reduced by 9.68%and the stress is reduced by 29.77%compared to the pre-optimization period,resulting in the optimization of the stability of the lower bearing.To the similar products of the structure of the optimization of the design provides a reference to the ideas that can be borrowed.关键词
