根据大型、超大型履带式推土机的作业特点与振动特征，研究了其行走系应采取的缓冲措施。对所建的减振模型参数进行了优化；根据阻尼减振材料的特性，对推土机驱动轮用橡胶缓冲装置进行了动态优化设计；对研制出的橡胶缓冲装置进行了试验研究，获得第一手数据。 According to the operating characteristics and vibration characteristics of the large-scale and ultra-large crawler bulldozers, the buffering measures that should be taken in their walking systems are studied. The parameters of the damping model were optimized. According to the characteristics of the damping material, the rubber buffer device of the bulldozer drive wheel was dynamically optimized. The developed rubber buffer device was experimentally studied and obtained first-hand. data.
