During the platform pipe calibration of ship piping, the calculation errors or process errors lead to the later rework. In view of such problems, the virtual simulation technology is used to verify the feasibility of virtual assembly of pipe calibration assembly operation process. The finite element meshing algorithm is used to find a reasonable process path, and the collision detection technology is used to make the model interference check. The results show that the method can find the problems during pipe calibration in advance and improve the work efficiency.
