Abstract
In the post-epidemic era, drone distribution has attracted increasing public attention because of its excellent contact-free characteristics and capacity to greatly improve the efficiency and reliability of material distribution. Combining land-air drones with logistics distribution, this design breaks through the limitations of the single-movement ability of traditional drones and land robots to fly in the air or move on the ground. Based on the collection and statistics of technical indicators related to logistics distribution, this paper focuses on the design of land-air conversion mode, and proposes an innovative land-air conversion mechanism composed of ball screw nut pair and multiple sets of gears to complete the design of the related mechanical structure of land-air logistics UAV. In addition, the mechanical system simulation of drones is carried out by ADAMS software. Moreover, the static and aerodynamic simulation analysis of UAVs is conducted by ANSYS software to optimize the overall structure.
