On the part of the design of nine - component thrust vector stand , an automatic hydraulic pressure original position calibration system , a scheme of original position calibration , and the great rigidity universal flexible combinatorial underprop are designed . by using the scheme of “ universal flexible combinatorial underprop plus software digital filter ” , the inherent frequency of test stand is improved , and the problem of test stand libration is solved . then , the resolving method of the disturbance between underprops of the moveable frame is proposed , and the disturbance revise equation is deduced 在推力矢量試車臺設計方面,設計了自動液壓原位校準系統、原位校準方案以及大剛度萬向柔性組合支撐;采用“萬向柔性組合支撐+軟件數字濾波”的方案,提高了試車臺動架的固有頻率,解決了試車臺動架的振動問題;提出了動架約束互擾問題的解決方法,推導了互擾修正方程;研究了九分力推力矢量測量誤差分析方法,并計算了推力矢量測量精度。
