| Abstract: | ![]()
By measuring the spatial coordinates of several points on the figure joints and slice joints of the toroidal field coils on HL-2M device, the outer contour planes of the coils are fitted with the spatial data of the points by the least squared method and the tilt angle of central axis is calculated by the spatial relation between the planes and the central axis. With the simplified model and numerical simulation, the tilt angles of different spatial points with several standard deviations of measurement are calculated. The average relative error of tilt angle is 0.10‰ and the relative standard deviation is 1.21‰ with a low standard deviation of metrology (σ=0.05mm). |
