The invention discloses a supporting structure of a two-degree-of-freedom test bed. The supporting structure comprises an oil tank installation platform and a supporting frame, wherein the supporting frame is of a tetrahedral structure composed of an upper cross beam, a lower cross beam and a supporting rod, a pitching rotating shaft is arranged between the lower cross beam and a foundation, and a transverse rolling rotating shaft of the test bed is formed between the upper cross beam and the oil tank installation platform; in addition, a pitching actuating cylinder and a rolling actuating cylinder are arranged. The design simplifies the structure of the test bed, construction is convenient, and installation precision is easy to guarantee; and composite angle rotation of the test bench capable of simultaneously controlling pitching/rolling can be realized, and the test bed is suitable for the test of a light-load tested system.

    一种两自由度试验台的支撑结构,含有油箱安装平台和支撑架,所述的支撑架是由上横梁、下横梁和支撑杆构成一个四面体结构,下横梁与地基之间有俯仰转轴,上横梁与油箱安装平台之间形成试验台的横滚转轴,另有俯仰作动筒和横滚作动筒。这种设计简化了试验台结构,施工方便,安装精度容易保证。且能够实现俯仰/横滚同时控制的试验台的复合角度转动,适用于轻载荷被试系统试验。
