Improvement of Structural Strength of Furniture Based on Finite Element Analysis
-
摘要: 运用ANSYS有限元分析软件对家具结构强度检测中发现的普遍问题进行理论分析，并选取松木床作为研究对象，根据家具力学性能国家标准中的试验方法，对床铺面集中静载荷试验进行有限元模拟，结果表明：松木床铺面无法满足强度安全要求。为此优化设计提高强度，选用改变床结构和换用重组竹材料2种手段并进行有限元分析，发现2种手段分别可提升床铺面安全系数至1.25和3.16，均有较好的强度优化效果。此外，使用重组竹可使得家具在保证强度前提下更加轻便，也将缓解国内木材短缺的现状，具有广泛前景。Abstract: Some universal problems found in the structural strength test of furniture were analyzed using ANSYS finite element analysis software. Pine wood bed was selected as the research subject. According to the test method in the national standard of furniture mechanical properties, the finite element simulation of the concentrated static load test of the bed surface was carried out. The results showed that the pine wood bed did not fulfill the requirements of strength safety. For this reason, the design was optimized to improve the strength. Two methods were investigated:altering the bed structure and substituting the bamboo scrimber as material, and the finite element analysis was performed. It was found that the two methods increased the safety factor to 1.25 and 3.16, respectively. In addition, the use of bamboo scrimber could make furniture lighter under the premise of ensuring strength, and might also alleviate the domestic lumber shortage, hence having broad prospects.
