Embodiment Construction
[0028] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0029] Such as figure 1 Shown is an axonometric view of a two-degree-of-freedom support system, which includes a rotating module ( figure 2 ), translation module (such as image 3 shown), measurement modules (such as Figure 4 shown), the protection module (as shown in Figure 5) and the interface module (such as Figure 6 Show).
[0030] Such as figure 1 and figure 2 As shown, the rotary module includes a rotary pair, which includes a turntable bearing (10) and a trolley platform (4), for simulating the pitching motion of an aircraft. Turntable bearings have small frictional damping moment and can withstand axial and radial loads.
[0031] Such as figure 1 and 3 As shown, the translation module according to an embodiment of the present invention includes two linear guide rails (11) and such as four slide blocks (9), which form a...
