某隐形飞机内埋式武器在弹射过程中,系统质心变化、外流场剧烈扰动等可能会引起武器姿态偏离,导致机/弹碰撞,因此在弹射系统中设置了同步机构。为取得同步机构角度和长度最优值,通过动力学分析软件ADAMS对同步机构进行参数化建模,用OPTDES-SQP非线性二次规划算法对同步杆的角度和长度进行仿真研究。研究结果表明,同步机构最优值为A=91.13°,l₁₁=l₁₃=45.01mm,l₃=3839.28mm,同步性能对A值变化最敏感,应以A值误差控制为主。

When stealth aircraft launches weapons, the change of system centroid or the interference from air-flow may lead to postural deviation of the weapon, and collision may be occured between the fighter and the weapon, so the synchronous system came into being. In order to get the optimal result of the synchronous system, the parametric model is built under the software ADAMS, the angle length and sensitivity are simulated under OPTDES-SQP. The result shows that A = 91.13°, l₁₁ = l₁₃ = 45.01 mm, l₃ = 3 839.28 mm is the optimal result, and A is more sensitive than others to synchronous system.
