Discrete topology optimization and lightweight design of thickener support legs
针对高效浓密机在工程应用中存在的体积庞大、耗材多、结构复杂等问题,提出基于离散体拓扑优化的支腿轻量化设计方法,旨在降低整机质量与制造成本.在确保结构力学性能的前提下,以最小化最大位移为优化目标,建立有限元模型开展静力分析,明确支腿受载特性.采用基于桁架结构的离散体拓扑优化方法构建初始优化模型,并在体积分数约束下进行结构重构,完成优化构型设计并进行仿真验证.结果表明:该优化方案在满足7级地震工况下结构强度要求的同时,实现了8.38％的减重,验证了方法的有效性,为浓密机支腿的轻量化设计提供了有力参考.
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.
