Abstract: By using the method of maximum error, the paper deals with the analysis of the static error of the six-component force test stand of solid rocket motors. The results show that its static error is mainly from the adjustment of the vertical axis of the adjustable support.The formulas for calculating the static errors of the thrust misaligment moment and up are derived The adjusting method of diminishing the static error of the vertical test stand is also discussed in the paper.
