摘要

为了优化大型振动筛侧板加强筋的布局,提出一种基于拓扑优化的侧板加强筋布局方法。建立以侧板刚度最大为目标的侧板加强筋布局的拓扑优化模型,根据拓扑优化所得伪密度分布云图对加强筋重新布局。对优化前后侧板进行模态分析和谐响应分析对比。与原侧板相比:新结构侧板的动应力下降56.5%,振动位移下降55.3%,一阶固有频率提高72.03%,各阶固有频率有效远离工作频率。

Abstract

In order to optimize the layout of the large vibrating screen side panel stiffeners,Topology optimization design was applied in structural design of the side panel stiffeners. The topology optimization model of side panel stiffeners which were based on the goal of maximizing the lateral stiffness of side panel stiffeners was established. According to the pseudo density distribution of the topology optimization,the stiffeners would be rewired. The modal analysis and the harmonic response analysis were done for the panels before and after optimization. Compared with the original side panel structure,the new side panel’s dynamic stress was reduced by 56. 5%,Vibration displacement was reduced by 55. 3%. In addition,the first natural frequency was improved by 72. 03%,the natural frequency was far from working frequency effectively.
