The three-dimensional model of tunnel heading and loading machine analyzed with static finite element method. According to the finite element stress calculation of＇ cloud images, the stress distribution is analyzed, on this basis, the structure design of the drive wheel is optimized. At last, the drive wheel is analyzed by modal analysis, the natural frequencies and vibration modes of the driving wheel are obtained. The resuhs show that the finite element analysis of the tunnel heading and loading machine＇s drive wheel not only verify the theory but also provide the evidence of the drive wheel improvement.
