浓密机支腿的离散体拓扑优化与轻量化设计研究
Discrete topology optimization and lightweight design of thickener support legs
摘要
Abstract
To address the large volume,high material consumption,and complex structures commonly found in high-efficiency thickeners,this paper proposes a lightweight design for support legs based on discrete topology optimization to reduce overall machine weight and manufacturing cost.While ensuring the structural mechanical performance,a finite element model was built to conduct static analysis and identify the loading characteristics of the support legs.Then,an initial optimization model was developed using a discrete topology optimization suitable for truss structures.Next,structure reconstruction was achieved under volume fraction constraints and the optimization configuration was designed and validated through simulation.Results show the proposed scheme reduces weight by 8.38％while satisfying structural strength requirements in a 7-magnitude earthquake.This paper may provide some insights into the lightweight design of thickener support legs.关键词
