为了改善现有机翼调姿系统精度，研究了一种机翼部件多Pogo柱并联调姿机构的误差建模问题。利用空间矢量链建立机翼部件调姿位移逆解方程，通过微分摄动法建立其末端调姿误差与机构几何误差源之间的传递矩阵，得到了包含63项几何误差源的映射模型。在此基础上，对影响末端位姿误差的几何误差源进行灵敏度分析。结果表明：调姿机构直线导轨沿各向角度和导轨间垂直度误差灵敏度较大。

In order to improve the existing wing position and pose adjustment system accuracy,the error source modeling problem of a passive parallel position and pose adjustment mechanism for wing parts with multi- Pogo stick is studied. By using space vector chain to set up wing parts of position and pose adjustment and displacement inverse equation,by differential perturbation method,its transfer matrix between terminal adjustable posture error and geometric error sources was established,and the mapping model which contained 63 geometry error sources was gained. Based on this,sensitivity analysis was conducted for the geometric error sources which effected end pose error. The results show that adjustable posture mechanism linear guide along the each angular deviation be-tween the guide rail and verticality sensitivity is bigger.
