According to the characteristics of the general tunnel structure, one type of the concrete spraying machine is designed and researched for convenient operation. Based on the work condition, the structure and dimensions of the mechanical are calculated, including the thickness and section size of each working arm. During the loading situation, the strength and stiffness of the key components are calculated by theoretical arithmetic. The concrete spraying machine structure is simulated for dynamic analysis comparison by Pro/E and Matlab software. The design method of the concrete spraying machine has certain directive significance for advanced product manufacturing.
