Embodiment Construction

[0011] The present invention is a beam-type three-way vibration isolator, which is composed of twelve elastic beams and ten rigid blocks. According to the use environment of the vibration isolator, the beams can be made of spring steel, stainless steel or non-metallic materials with good elastic properties, and the rigid blocks are guaranteed In the case of reliable connection with the beam, a material different from the beam can be selected. The cross-section of the twelve beams must be flat and rectangular, and the cross-sectional aspect ratio can be designed according to the rigidity requirements without losing stability. The connection between the beam and the rigid block can be connected by bolts, or the two ends can be welded together with the rigid block. The lengths of the elastic beams 1, 2, 3, 4 are the same, the lengths of the elastic beams 5, 6, 7, and 8 are the same, and the lengths of the elastic beams 9, 10, 11, and 12 are the same. The space placement of the twelve...

Abstract

The invention belongs to the field of vibration control technology on the electromechanical device, specifically, a beam type three-direction vibration isolator. The vibration isolator is composed of 12 spring beams. Wherein, two groups of spring beams (four beams) are respectively connected by a rigid block to form a crisscross beam support, two crisscross beam supports are formed a whole spacial crisscross beam support by four equal-length vertical spring beams by eight rigid blocks. The upper and the lower rigid blocks in the middle are respectively connected with a vibrating body and vibration isolation object; in this way, the vibration isolation purpose can be realized at three directions. The vibration isolator is simple in structure, low in cost, convenient to install and can be applied for the vibration isolation in fields of aviation, spaceflight, electronic product, mechanical equipment, transportation, communication and so on.

Description

Technical field [0001] The invention belongs to the technical field of vibration control of electromechanical equipment, and specifically relates to a beam-type three-way vibration isolator. Background technique [0002] Electronic products, transportation vehicles, ships, airplanes, rockets, aerospace vehicles, etc., are inevitably affected by the external environment during transportation, exercise and launch, and sometimes strong vibrations will affect their normal operation. Cause damage. The common method for vibration control of the above-mentioned equipment is to perform vibration isolation treatment, that is, to install a vibration isolator between the product and the external environment. [0003] At present, the commonly used vibration isolators include metal spring vibration isolators, rubber vibration isolators and air spring vibration isolators. These vibration isolators have many advantages and have been widely used in the field of vibration control. When these vibr...
