摘要
本文以电动餐桌支架三维模型为研究对象,利用UG高级有限元仿真模块,赋予模型材质为镀锌钢,对模型底部施加固定约束及支架托盘施加-4000N力载荷并进行求解。仿真结果显示:电动餐桌支架最大形变位移形变位置为支架转盘承托截面外沿,位移为0.141mm;最大应力分布位置为支架转盘承托截面中心,应力为22.05Mpa。研究表明;在承重为400kg时,镀锌钢电动餐桌支架满足设计要求。本文研究结果将为家具企业进行电动餐桌设计及支架选购提供科学指导,对提高电动餐桌的使用寿命及安全性具有重要意义。
This paper takes the three-dimensional model of the electric dining table bracket as the research object and uses an advanced finite element simulation module Unigraphics NX to simulate the galvanized steel texture of the model material.Then,the simulation imposes fixed constraints on the bottom of the model and applies a-4000N force load on the bracket tray.The results show that:the maximum deformation displacement of the electric dining table happens at the outer edge of the support section of the bracket turntable,which is 0.141mm;and the maximum stress distributed at the center of the support section of the bracket turntable,which is 22.05Mpa.The research implies that the galvanized steel electric dining table bracket can meet the design requirements when the load is 400kg.The research results of this paper will provide scientific guidance for furniture enterprises to design and purchase electric dining table brackets,which is of great significance to improve the service life and safety of the electric dining table.
