The frequency of the structure of system in the y-axis direction；
In the direction of the x axis because cycloid is stopped by sliding support, the length from sliding support to mass ball is to have
Pendulum length L' is imitated, its numerical value is determined by formula (2), wherein, fxIt is the frequency of controlled structure in the direction of the x axis；
Described sliding support is slided with baffle plate by roll mode, i.e., holding plate is " several " letter stencil, is provided with placement thereon
The circular hole of ball, Circularhole diameter are less than ball diameter.
Through hole on described sliding support be have two halves annular retaining plate shape into, the inner side of semi-circular holding plate is card
Groove, ball are limited in neck.
Beneficial effects of the present invention：The present invention solves traditional suspension-mass pendulum vibration insulating system and there was only asking for single-frequency
Topic.In Practical Project, due to the unicity of suspension-mass pendulum frequency, can only control structure some direction vibration.Profit
With the sliding support of design, make pendulum that there is different effective pendulum lengths in the both direction of horizontal plane, so that pendulum has difference
Frequency, the vibration of more preferable control structure in different directions.

Embodiment
Below in conjunction with accompanying drawing and technical scheme, embodiment of the invention is further illustrated.
A kind of two-way suspension-mass pendulum damping system, including mass ball 1, cycloid 2, sliding support 3, semi-circular holding plate
4th, baffle plate 5, holding plate 6, connecting rod 7, bottom plate 8.
The present invention overall schematic, face view, left view as Figure 1-Figure 4, structure such as Fig. 5 institutes of sliding support
Show.Holding plate 6 is installed in the track in the outside of sliding support 3 and ball is set, allow bearing 3 on the track of baffle plate 5 from
By slip.It is connected by screw bolts, and is fixed on the ad-hoc location of cycloid 2 between two sliding supports, it is ensured that bearing 3
Slide along the y-axis direction, so that pendulum has different effective pendulum lengths on x, y-axis direction.To reduce cycloid 2 and the edge of bearing 3
Between friction, the service life of superior trochoid 2, two semi-circulars holdings are set at the edge that cycloid 2 and bearing 3 rub
Plate 4, and ball is installed on semi-circular holding plate 4.One end of connecting rod 7 is welded on baffle plate 5 again, the other end is welded to bottom plate
On 8, it is ensured that baffle plate 5 is fixed in use.In order to make cycloid 2 preferably fixed and swing, cycloid 2 is using flexible
Steel strand wires, one end is welded on the central point of bottom plate 8, and the other end knots through the Q-RING on the top of mass ball 1, and uses aluminium alloy
Gland ring is fixed, and so ensures that cycloid 2 very firm can play a role；Bolt hole 9 is stamped in the surrounding of bottom plate 8, can be passed through
