摘要:

本文用最大误差方法,对固体火箭发动机六分力立式试验台的静态误差进行了分析.分析结果是,其静态误差主要来源于动架纵轴的调整.并建立了发动机推力偏心距和推力偏心角的静态误差计算公式.文中也谈到减小立式试验台静态误差的调整方法.

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.
