Specific embodiment
As shown in Fig. 1,2,3,4 and 5, a kind of damper based on variable cantilever beam structure, it is characterised in that cushion blocking 1,
Gland 2, bushing 3, damper mounting plate 4；
The cushion blocking 1 is bowl-shape metalwork, and " bowl " bottom is equipped with aperture, and " bowl " wall is distributed uniformly and circumferentially by several
, form from " bowl " bottom to the cantilever beam of external radiation, the thickness of " bowl " wall is from center outward by thick thinning；
The gland 2 is hemispherical metalwork, and upper surface is equipped with outer-hexagonal step, and lower surface is hemisphere face, and center is equipped with
Threaded hole；
The bushing 3 is metalwork, and lower surface is equipped with outer-hexagonal step, and upper surface is hemisphere face, and the center of upper surface is set
There is stud, center stud is equipped with through-hole；
The damper mounting plate 4 is metal flange, and upper and lower surface is equipped with hemispherical deep gouge, and deep gouge center is equipped with through-hole；
Bushing 3, cushion blocking 1, damper mounting plate 4, cushion blocking 1, gland 2 are successively assembled according to sequence from top to bottom,
The curved surface of bushing 3 and gland 2 and the negative camber of cushion blocking 1 cooperate, the curved surface deep gouge of damper mounting plate 4 and cushion blocking 1 it is outer
Curved surface cooperation；
By adjusting cushion blocking 1, gland 2, bushing 3, the curve form of damper mounting plate 4, thickness, cantilever beam number,
Resiliency characteristics when careful design compression may be implemented；
By taking the vibration damping of Payload Attach Fitting as an example, connection type is that damper and Payload Attach Fitting are connected by screw, delivery
Support platform and damper are connected by screw.
The course of work:
As shown in fig. 6,1 outer rim of cushion blocking is relatively thin, rigidity is low, and bigger closer to axle center wall thickness, rigidity is higher；Amplitude is larger
When, cushion blocking 1 is mobile to axle center with the contact position of gland 2 or bushing 3, and while the arm of force shortens, the average thickness of cantilever becomes
Greatly, therefore there is the characteristics of " small rigidity when small amplitude, when large amplitude big rigidity ", when damper bears Random Vibration Load,
The vibration of the small amplitude of high frequency can be isolated in cushion blocking 1 by flexible deformation, simultaneously because its rigidity increases when amplitude increases, it can
To realize the effect for inhibiting resonance.
