Abstract:

To improve the tire performance of puncture-proof,explosion prevention,safety and bullet-proof,a kind of new mechanical elastic wheel used for military vehicle was put forward. Finite element model and elastic mechanics model were established by analyzing the structure of the new mechanical elastic wheel and were calculated respectively.The deformations obtained by the two models are coincide and show the finite element model is a very good response to the deformation of the wheel.Rolling radius was solved from the finite element model and trafficability was analyzed.The influence factors of drawbar pull force's component forces were discussed in detail.The theoretical supporting for the wheel future design was provided from the discussion.Comparing with the ordinary pneumatic tire in the trafficability,the new mechanical wheel has more advantages.
