Improvement of Structural Strength of Furniture Based on Finite Element Analysis

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.
