Dynamic simulation of crawler excavator walking mechanism

In order to develop a mechanical simulation experiment, a dynamic simulation of crawler excavator walking mechanism is designed. The performance of walking mechanism of excavator is tested by dynamic simulation. According to the data analysis, it is known that crawler walking mechanism is an important part of mine excavator and a walking device with better adaptability than wheeled walking mechanism. The crawler can travel on a road with poor working conditions, such as deep snow, swamp, mud and sand, while the wheeled devices cannot work in these conditions. Therefore, in combination with the actual working conditions of excavators, two kinds of mines are simulated and studied. The dynamic simulation of the meshing force between the driving wheel and the track plate during the walking process is carried out, and the movement state of the driving wheel in the forward and backward conditions is simulated and analyzed. The experimental results show that the grounding of the crawler device is much smaller than that of the wheel type, and the load impact can be greater than that of the wheeled type. In addition, the working environment of the excavator is very bad, and it is often run in the mines in the sand and mud. Through simulation analysis, it is concluded that the walking mechanism of crawler excavator is more efficient and convenient than the traditional wheeled excavator.
