摘要

为研究内支撑轮胎爆胎对火炮行驶性能的影响，由于安全性实验危险系数大，本文利用虚拟试验的方法来研究牵引火炮行驶过程。利用多体动力学软件建立了火炮行驶模型，模拟其行驶过程，得到了速度对其的影响，并与传统的充气轮胎进行了对比分析。仿真结果表明：内支撑轮胎自身结构合理，应力分布均匀，速度对火炮侧偏性能有着重要影响，较传统充气轮胎的性能有所提高，为内支撑轮胎试验和使用提供了理论数据。在仿真结果的基础上，通过基地试验验证了仿真结果的正确性。

Abstract

Abstract: As it is dangerous to implement a physical test for studying the influence of internal supporter tire blowout to the performance of artillery towing, we carried out virtual experiments to study its dynamic behavior based on PRO/E. Based on the force analysis of tire structure, the calculation of forces are specified. We constructed the finite element model of tire and achieved its diagram of stress distribution in the later simulation. With the software of Recurdyn, we analyzed the marching behavior of internal supporter tire at different speeds, and compared with that of conventional pneumatic tire. The experiment result shows that as the internal supported tire has a reasonable structure, its stress is well-distributed. The sidepartial acceleration can be apparently affected by speed. The internal supporter tire has a better performance than conventional pneumatic tire. Our study lays a theoretical foundation for the application of the internal supporter tire.
