Abstract

Abstract

The landing gear is one of the important components of the aircraft. In order to reduce the structural weight and stress concentration, combined with the development of 3D printing technology, on the premise of no increase in the total mass and no breakthrough in the overall dimension, the original cross structure is changed into a hollow cylinder structure. With reference to the bamboo structure, two bionic structures of brake rod on landing gear are designed, and further parameter optimization is carried out by using the response surface method. The simulation results show that the quality of the two bamboo-like structures is reduced by 17% and 14.98%, respectively, and the maximum equivalent stress is reduced by 57.34% and 57.90%, respectively. It shows that the imitation bamboo structure has a good effect on reducing the maximum equivalent stress. The optimization method has practical significance for the lightweight design of rod structure, and can be popularized.
