The invention relates to a multi-degree-of-freedom testing device. The device is composed of a two-degree-of-freedom parallel testing test bench and a multi-wheel centering rolling test bench. The multi-wheel centering rolling test bench is arranged on the two-degree-of-freedom parallel testing test bench and fixedly connected with the two-degree-of-freedom parallel testing test bench, and the multi-wheel centering rolling test bench is used for simulating rotation in the horizontal axis direction. The multi-wheel centering rolling test bench is composed of two driving rings and one rolling body, the driving rings comprise an upper ring and a lower ring, the lower ring is fixedly arranged on the two-degree-of-freedom parallel testing test bench, the upper ring and the lower ring are connected together through a rotating shaft, and the driving rings are used for clamping the rolling body. By adding the multi-wheel centering rolling test bench, rolling in the horizontal axis direction is added on the basis of rotation in the horizontal axis direction, an aircraft fuel tank in the motion state is simulated through the rolling body, the fuel tank state in the simulated flight state is improved, and precious reference data are provided for fuel tank design.

    本发明涉及一种多自由度测试装置,该装置由1台两自由度并联测试试验台和1台多轮定心滚转试验台组成;多轮定心滚转试验台设置在两自由度并联测试试验台上,与两自由度并联测试试验台固定连接,多轮定心滚转试验台用以模拟沿着水平轴线方向上的旋转;多轮定心滚转试验台由2台驱动环和1台滚动体组成,驱动环包括上环和下环,下环固定设置在两自由度并联测试试验台上,上环与下环通过转轴连接在一起,驱动环用以夹持滚动体,通过增加多轮定心滚转试验台,实现在水平轴线方向上的转动的基础上增加沿着水平轴线方向上的滚动,利用滚动体来模拟运动状态下的飞机油箱,提高获取模拟飞行状态下的油箱状态,为油箱设计提供宝贵的参考数据。
