摘　　要：通过对发动机柔性喷管推力矢量控制伺服系统动态特性进行了研究,研制了一种能够真实反映柔性喷管在全轴摆动状态下的动态特性的试验系统;两组角位移传感器输出轴通过十字型构件组合在一起,正交配制,线位移传感器则和十字型构件上固定的一组角位移传感器输出轴联结在一起,组成极坐标传感器,可以准确实时获得柔性喷管在全轴摆动过程中的六自由度数据;该真摆角测量系统能够用于测量固体发动机柔性喷管空间摆角、摆心变化量及推力矢量控制伺服系统性能特性,具有广阔的应用前景和良好的经济价值。By studying the dynamic characteristics of Flexibility Nozzle of the Motor Thrust Vector Control,develop a experiment device that can reflect dynamic characteristics of the Flexibility Nozzle in the state of the omni-axial movable veritably.Two sets of output shaft of the angular displacement sensor are grouped together by the cross,orthogonal configuration,then the linear displacement sensor picks up a set of output shaft of the angular displacement sensor on the cross together,constituting the Polar Sensor.It can be obtained the six-degree-of-freedom data of the Flexibility Nozzle in the state of the omni-axial movable veritably in real time.The true angular measuring system can be used for measuring the space angular of the Flexibility Nozzle of the solid engine、the variable quantity of the pivot point and the performance characteristics of Thrust Vector Control,having expansive application prospect and far-reaching application value.
