摘　　要：针对越野汽车的特殊行驶环境,为了提高轮胎的防刺破、防爆胎和安全性能,提出一种新型机械弹性安全车轮。在深入分析其结构的基础上,建立了有限元模型,并求解了各个方向的刚度。在ADAMS中建立了包括新型机械弹性车轮在内的整车模型,经随机路面输入仿真分析得出如下结论:基于机械弹性车轮的整车符合平顺性要求且满足普通轮胎的平顺性规律。在高速下,基于子午线轮胎整车的平顺性略优于基于新型机械弹性车轮整车的平顺性。To improve the tire performance of puncture -proof ,explosion prevention and safety ,a kind of new mechanical elastic wheel used for off -road vehicle was put forward .Finite element model was established by analyzing the structure of new mechanical elastic wheel and kinds of stiffness of the wheel were simulated .The vehicle model concluding the new mechanical elastic wheel was built in the software ADAMS .The results show that the vehicle concluding the new mechanical elastic wheel meets the comfortability requirements and ride comfort regularity of pneumatic tire .In high speed ,the ride comfort of vehicle concluding the preumatic tire slightly better than the new mechanical elastic wheel .
