The invention provides a two-piece type prestress hanging basket device of a shimmy test bed. Comprising a main body stand column (1), a sliding plate (2), a vertical loading cross beam (3), a hanging basket component (4), a loading hydraulic cylinder (12) and a force measuring platform (14), according to the device, 16 groups of roller sliding blocks (6) are connected with a sliding plate (2) of a main body stand column (1) in a sliding mode, the 16 groups of roller sliding blocks (6) guide vertical movement of a hanging basket component (4), and horizontal force borne by the hanging basket component (4) is transmitted to the main body stand column (1). A limiting hole (8-1) is formed in an upper bearing plate (8) of the hanging basket component (4), and when a tire bursts, a limiting screw (13) pulls the hanging basket component (4) through the limiting hole (8-1), so that the tire is prevented from being excessively pressed downwards. Compared with a traditional welding type hanging basket device, the device has the advantages of being simple in structure, light in motion mass, high in loading response speed and the like, the dynamic characteristics of the aircraft tire can be better simulated, and the test result is more real and reliable.

    本发明提供了一种摆振试验台两片式预应力吊篮装置;包括:主体立柱(1)、滑板(2)、垂直加载横梁(3)、吊篮部件(4)、加载液压缸(12)、测力平台(14);本发明装置通过16组滚柱滑块(6)与主体立柱(1)的滑板(2)滑动联结,16组滚柱滑块6对吊篮部件(4)的垂直运动进行导向,并将吊篮部件(4)受到的水平力传递到主体立柱(1)。吊篮部件(4)的上承载板(8)上设有限位孔(8‑1),爆胎时,限位螺杆(13)通过限位孔(8‑1)拉住吊篮部件(4),防止轮胎过度下压。本发明与传统焊接式吊篮装置比具有结构简单,运动质量轻,加载响应速度快等优点,能够更好的模拟航空轮胎的动力学特性,试验结果更加真实可靠。
