摘要

本文对货架面积为75 m2的冷冻干燥设备干燥室进行了有限元分析，并对其结构进行了优化。首先，确定了ZLG-75冷冻干燥设备干燥室的结构设计。然后利用Solid works对干燥室本体进行三维建模。并利用ANSYS软件对干燥室本体的强度和刚度进行了分析。比较了不同壁厚和不同加筋数量的干燥室内的变形程度。对整个结构进行优化设计，最终确定干燥室壁厚为8 mm，钢筋间距为410 mm。关键词:冷冻干燥设备;烘干室;优化;有限元分析

Finite Element Analysis of the Drying Chamber of Freeze-drying Equipment

In this paper, the finite element analysis of the drying chamber of the freeze-drying equipment with a shelf area of 75 m2 is carried out, and its structure is optimized. Firstly, the structural design of the drying chamber of ZLG-75 freeze-drying equipment was determined. Then use Solid works to carry out three-dimensional modeling of the drying chamber body. And using ANSYS software to analyze the strength and stiffness of the drying chamber body. Comparing the degree of deformation in the drying chambers with different wall thicknesses and different number of reinforcing ribs. Optimized design for the entire structure, It was finally determined that the wall thickness of the drying chamber was 8 mm and the spacing of the reinforcing bars was 410 mm. Keywords-Freeze Drying Equipment; Drying Room; Optimization; Finite Element Analysis
