摘　　要：为了研究履带式集材拖拉机的行驶平顺性，将其简化为三自由度振动力学模型。以国产集材－５０型拖拉机为对象，进行了模拟计算和实地试验，其模拟计算结果与试验结果能较好吻合。此外还研究了各振动参数对行驶平顺性的影响。In this article, the tracked skidding tractor seat system is simplified into a three degrees of freedom ride model to be used to research riding comfort of tracked skidding tractor and a simulation method of computer used in the random vibration of the tractor is presented. With the tracked skidding tractor of J 50 type made in China, the researches have made field test and simulating calculation in computer. The results acquired are identical favourably. In addition, the authors study the influences of construction parameters on riding comfort of the tracked skidding tractor and give some suggestions to improve the riding comfort that the proper adjustment of the parameters of suspension and seat of the tractor would have prominent effect.
