The invention provides an in-shaft control five-degree-of-freedom anti-twisting device for a coaxial dual-rotor test bed. The device comprises an upper rotor control shaft, an upper rotor control shaft hollow pipe, an automatic inclinator moving ring, an automatic inclinator fixed ring, an actuator, an actuator support, a five-degree-of-freedom anti-twisting disc and a bearing support. Through the five-degree-of-freedom anti-twisting device, the motion of a non-rotating part in the in-shaft control system in the twisting direction is restrained in a limited space, meanwhile, other directions are free, and it is ensured that a control load cannot be transmitted to a test bed body through an anti-twisting mechanism; the invention provides an in-shaft control five-degree-of-freedom anti-twisting device for a coaxial dual-rotor test bed, which realizes the constraint of the motion in the twisting direction of an in-shaft control system, ensures that the control load is not transmitted to the test bed body through an anti-twisting mechanism, and ensures the accuracy and effectiveness of the measurement of the control load.

    本申请提供了一种共轴双旋翼试验台轴内操纵五自由度防扭装置,所述装置包括:上旋翼操纵轴、上旋翼操纵轴空心管、自动倾斜器动环、自动倾斜器不动环、作动器、作动器支座、五自由度防扭盘、轴承支座;其中,通过五自由度防扭装置,在有限空间内,约束了轴内操纵系统中非旋转部件的扭转方向运动,同时其余方向自由,确保了操纵载荷不会经防扭机构传递至试验台体;本申请提供了一种共轴双旋翼试验台轴内操纵五自由度防扭装置,实现了轴内操纵系统的扭转方向运动的约束,同时确保了操纵载荷不会经防扭机构传递至试验台体,保证了操纵载荷测量的准确性与有效性。
