Abstract: The study on structure optimization design of modified wood furniture tenon structure based on the finite element analysis of ANSYS has a very important significance. On the one hand, it can enhance the functionality of the furniture. On the other hand, it can effectively reduce the destruction of natural resources. Chinese traditional furniture tenon connection technology with widely application and mature process is one of the commonly used connection technologies in China’s construction and furniture manufacturing. After a certain modification of processing, wood used in the production of furniture can meet the demand of density and bearing, which is conducive to the modernization design of modern furniture. For optimization design of furniture tenon structure through the finite element analysis software NASYS, parametric modeling was firstly made by using a T-shaped tenon structure of modified poplar as the research object, and setting the size of tenon structure. On this basis, the optimization design was carried out step by step, and finally the results of the feasibility design sequence were obtained. From the optimization results, it can be seen that in the final feasible design sequence, the optimal tenon length ratio and tenon thickness ratio were 74.0% and 61.6%. In order to verify the performance of the optimized design results, five groups of tenon structure were processing product and made with the load test. Through the experiment, we can see that the rigidity index of tenon structure showed a decreasing trend and the maximum loading capacity was increased, which indicates that the effect of optimum design is to meet the initial purpose of optimization design.
