Abstract: Taking the traction seat legs as the research object, by changing the structure, reducing the weight and reducing the stress concentration, the purpose of improving the safety factor of the structure and lightweight is achieved. Firstly, a three-dimensional model of the traction seat legs and mounting plate is established, and the static loading condition of the traction seat leg is analyzed by using ANSYS; Secondly compares the strength of each leg under the same structure, different thickness, and the same thickness and different structures, so as to determine the optimal structure; Finally, the product is compared with the existing mature products. The results show that under the premise of reducing the quality by 8.2%, the safety factor is increased by 23% compared with the existing mature products, which not only improves the strength of the product, but also reduces the weight, and the optimization is more reasonable, and at the same time provides a basis for the optimization design of the traction seat legs in the future.
