The invention relates to ground test equipment, in particular to a gravity compensation device for a one-dimensional turntable ground test, which comprises a conical coupling, an air bearing, a pressure sensor and a mounting platform, and a stator of the air bearing is connected with the installation platform, a rotor of the air bearing is provided with a pressure sensor, the pressure sensor is connected with the lower end of the rotor of the one-dimensional rotary table through a conical coupler, and the upper end of the rotor of the one-dimensional rotary table is used for installing an external load. By using the equipment, the angular contact bearing of the one-dimensional rotary table is not influenced by external load gravity any more, the service life of the angular contact bearing is prolonged, meanwhile, the pressure sensor can be used for accurately obtaining the counteraction of the air bearing for counteracting the gravity of the one-dimensional rotary table, and the reliability of a ground test is ensured.
本发明涉及一种地面试验设备,尤其涉及一种一维转台地面试验用重力补偿装置,该装置包括锥形联轴器、气浮轴承、压力传感器以及安装平台;气浮轴承的定子与安装平台连接,气浮轴承的转子上装有压力传感器,压力传感器与一维转台的转子的下端通过锥形联轴器连接,一维转台的转子的上端用于安装外部负载。该设备的使用使得一维转台的角接触轴承不再受到外部载荷重力的影响,延长了角接触轴承的使用寿命,同时利用压力传感器能够准确的获悉气浮轴承用于抵消一维转台重力的反作用的大小,确保了地面试验的可靠性。
