Analysis of Force Transmission Characteristics of Modular Deformable Tire

摘要

In order to improve the explosion-proof, puncture-proof and safety performance of tires, a new type of modular deformable tires which can be used in complex road conditions has been put forward. The main innovation is the absence of so-called inner tubes and the modular design of the tire - which mainly consist of six petal-shaped connecting blocks and wheel frames. Firstly, this paper analyzes the structure and working principle of the tire. On this basis, the mechanical modeling of the tire under driving and braking conditions has been established. At last, through ADAMS software, the dynamic simulation of this tire under four circumstances of driving, accelerating, decelerating and braking has been carried out, and the response characteristic curves have been obtained The simulation results show that the force transmission performance of the modular deformable tire is rather good under the above four conditions. The simulation results provide a theoretical foundation and guidance for the structural design of new modular deformable tires.
