Tracked vehicles have the advantages of less ground pressure, better performance, etc., but the bad working environment makes it more vibrant, which has a great influence on the ride comfort. Therefore, a method for analyzing the ride comfort of tracked vehicles based on nonuniform coefficient of link was proposed. Firstly, by analyzing the correlation theory of the nonuniform coefficient of link, it was concluded that the main factors affecting the nonuniform coefficient were the distance of track link and the radius of the root circle of the driving wheel. Then, based on the RecurDyn dynamics software Track (LM) subsystem, the track walking devices with nonuniform coefficients of 1.043, 1.094 were modeled respectively, and the dynamics simulation was performed under the uniform motion condition of the hard ground, the influence of nonuniform coefficient on vehicle ride comfort was discussed in three aspects, which included the force between the tracked plate and the ground, the force between the tracked plate and the driving wheel, and the force between the supporting wheel and the ground. The results showed that the nonuniform coefficient could be reduced by reducing the distance of track link and the effect of uniformity coefficient of 1.043 on the vehicle ride comfort was significantly greater than that of 1.094. It provides practical reference value for the design and research of tracked vehicles.
