TBM TBM TBM cutterhead design system for adjusting the aperture ratio a method for calculating the aperture ratio using the same and a recording medium recording a computer-readable program for executing the method

摘要

The design information obtaining unit obtains the disk cutter arrangement design information of the TBM cutterhead from the disk cutter arrangement design drawing of the TBM cutterhead, and the drawing calculating unit for the interference check determines the area area of the holder including the disk cutter from the disk cutter arrangement design information. A drawing for an interference check displayed corresponding to each cutter is calculated, and the problem area determining unit determines whether the areas of the holder corresponding to different disk cutters overlap each other on the drawing for checking the interference, and the problem area solving unit partially When the holder regions overlap each other, the overlapping regions of some holders are rotated with respect to the rotation axis of the TBM cutterhead, and the arrangement information calculating unit calculates the arrangement information of the disc cutter so that all the holder regions of the cutterhead do not overlap each other, , The development drawing calculation unit calculates the development drawing of the TBM cutter head according to the calculated arrangement information.
