为了在实验室条件下检测导弹关键部件的抗过载能力,提出了一种离心转盘模拟试验方法。根据合成加速度的二维矢量分配原理,利用离心机带动转臂提供持续的动态加速环境;采用位置速度时间运动控制模式,利用转盘对其合成加速度实时跟踪和矢量分配,进行二维动态加速度的同步加载,实现导弹加速度过载环境的模拟。仿真和试验结果表明了该方法的可行性和有效性。

To test anti-overload ability of missile key components under laboratory conditions, a test method based on a turntable and a centrifuge was proposed. According to the vector distribution principle of synthetic acceleration, the continuous dynamic acceleration environment was reproduced by the centrifuge. The real-time tracking and vector distribution of synthetic acceleration were achieved by the turntable based on the motion control mode of position-velocity-time. A two-dimensional dynamic acceleration was loaded synchronously, therefore, the acceleration overload environment for missiles was simulated. The results of simulation and experiment demonstrate feasibility and effectiveness of the proposed method in this paper.
