Abstract

The magnetorheological high-damping shock absorber based on the metal rubber porous material comprises a hollow shell, a hemispherical shock absorption element made of porous metal rubber is fixedly connected to the interior of the shell, a movable rod is fixedly connected to the middle of the hemispherical shock absorption element, and a fixed rod fixedly connected to the shell is coaxially arranged on the opposite face of the movable rod; and a shockproof pillow is arranged between the fixed rod and the movable rod, and a cavity in the shell is filled with magnetorheological fluid. The damper has the prominent characteristics that the metal rubber with high damping performance is adopted as a damping element, the magnetorheological fluid and the metal rubber damping element are organically combined, and when the damper is subjected to an external load, the damping of the damper is variable based on the metal rubber with the porous structure characteristic. The device is simple in structure, low in cost and suitable for various severe environments.

Description

Technical field [0001] The present invention relates to a magnetore-vibration damping damper based on a metal rubber pore material, which is a vibration damping method thereof. Background technique [0002] The damping technology plays a pivotal position in the field of civil construction, ship ship construction, aerospace construction. Many engineering structures, industrial equipment and instruments are too large vibration load, often cause damage to the instrument and equipment, shortened mechanical parts, low equipment accuracy, and reliability, etc., may result in irreversible hazards. For equipment damping degradation in aerospace emissions, high damping properties dampers will be important equipment in key technologies. [0003] Metal rubber is a new type of elastic high damping material, from different grades and diameter fine metal wire spiral winding, helical spiral pitch stretch, blank equipment, cold punching, post-treatment, etc. series of process equipment Based, th...
