Abstract:
According to the random error effect analysis, the influence of the cable length error and the outer joint coordinate error on the cable force was analyzed, and the reasonable error control index was determined. Three kinds of the cable length error distribution models with the fixed value distribution, the uniform distribution and the normal distribution were compared. The influence of the length errors of the ring cable and the radial cable on the cable force was discussed, and the error control standards of different cable lengths were discussed. The results show that the ring cable force is less influenced by the length error of the radial cable. The influence of the ring cable length error on the radial cable and that on the ring cable are basically the same. Smaller the limit of the cable length error, larger the limit of the installation error of the outer joint. Different outer joint coordinates have different installation error limits, and the error limit of the higher site is smaller than that of the lower site. To meet the requirements that the cable tension error is not more than ±10%, the control indexes of this case are the production length error of the cable no more than ±0.01% of the cable length, the lower joint coordinate error of the outer node in radial direction no more than ±83 mm, and the higher joint coordinate error of the outer node in radial direction no more than ±67 mm.
