Problems solved by technology

Existing magnetorheological rubber shock absorbers generally include a vibrating table frame, a support seat and a shock absorber installed between the vibrating table frame and the support seat. The shock absorber includes a hydraulic cylinder and a coil located in the hydraulic cylinder. The piston rod and the cylinder barrel of the hydraulic cylinder are filled with magnetorheological fluid. The cylinder surfaces of the upper piston head and the lower piston head of the piston rod of the hydraulic cylinder are smooth surfaces, which can provide limited damping force, and its working efficiency is still to be determined. further improvement

Embodiment Construction

[0014] The present invention will be further described now in conjunction with accompanying drawing.

[0015] Corrugated cylinder magnetorheological rubber shock absorber of the present invention, as figure 1 , 2 As shown, it includes a vibrating table frame 1 , a supporting base 2 and a magneto-rheological damper 3 installed between the vibrating table frame 1 and the supporting base 2 .

[0016] The magnetorheological shock absorber 3 includes a hydraulic cylinder 31 and a coil 32 arranged in the hydraulic cylinder 31. The hydraulic cylinder 31 includes a cylinder barrel 311 and a piston rod 312. The space between the piston rod 312 and the cylinder barrel 311 is filled with magnetorheological shock absorbers. liquid. The magnetorheological fluid is injected through two holes on the bottom plate 7, and the two holes are sealed by a tapered pipe thread hexagon socket plug 71. The joint between the piston rod 312 and the cylinder 311 is sealed by an O-ring 315 , and the spa...

Abstract

The invention discloses a magnetic-rheologic rubber shock absorber with a corrugated cylindrical surface, comprising a shocking table frame, a supporting seat and a magnetic-rheologic shock absorber, wherein the magnetic-rheologic shock absorber is arranged between the shocking table frame and the supporting seat and comprises a hydraulic cylinder and a coil arranged in the hydraulic cylinder; magnetic-rheologic liquid is filled between a piston rod and a cylinder barrel of the hydraulic cylinder; a rubber block is padded between the cylinder barrel of the hydraulic cylinder and the shocking table frame; and the cylindrical surface of an upper piston head or a lower piston head of the piston rod of the hydraulic cylinder is in a corrugation shape. Compared with the prior art, the invention increases the damping force which can be provided by the shock absorber by replacing the smooth cylindrical surface of the piston head with a corrugated surface and can double or triple the efficiency of the traditional magnetic-rheologic shock-absorbing device.

Description

technical field [0001] The invention relates to a structure of a vibration damping device, in particular to the application of rheological technology to the vibration damping device. Background technique [0002] At present, there are many kinds of vibration damping devices used in the field of construction machinery. Among them, magnetorheological rubber dampers, which use rheological technology to achieve vibration damping, are due to their semi-active control. And the advantages of wide adjustable range of damping coefficient, fast response speed, low energy consumption, and no pollution to the environment have gradually become the mainstream of vibration damping devices. Existing magnetorheological rubber shock absorbers generally include a vibrating table frame, a support seat and a shock absorber installed between the vibrating table frame and the support seat. The shock absorber includes a hydraulic cylinder and a coil located in the hydraulic cylinder. The piston ro...
