2results about How to "Good damping function" patented technology

This utility model relates to the field of pneumatic double-layer valve technology, and more particularly to a programmable controller for a pneumatic double-layer valve. It includes a base plate, with two fixing blocks fixedly connected to both sides of the base plate surface. A fixing rod is fixedly connected to one side of the two fixing blocks facing each other. A first spring is sleeved on the surface of the middle end of the fixing rod, and sliding frames are fixedly connected to both ends of the first spring. The sliding frames are slidably connected to the surface of the fixing rod. This utility model has the advantages of good vibration damping and effectively extending the service life of the controller. In actual use, the coordinated use of the base plate, fixing blocks, fixing rod, first spring, sliding frame, rotating plate, and fixing frame effectively dampens the vibration generated during equipment operation, preventing damage to the internal components of the controller and significantly improving its stability and durability.

This invention discloses a double-layer clamp for aircraft piping with nonlinear vibration reduction function. The device includes an inner clamp, an outer clamp, clamp gaskets, fastening bolts, and fastening nuts. A certain constraint gap exists between the inner and outer clamps. Both the inner and outer clamps are assembled to the aircraft body using fastening bolts and nuts. The inner clamp consists of an inner clamp metal band and an inner clamp bushing; the outer clamp also consists of an outer clamp metal band and an outer clamp bushing. Both the inner and outer clamp bushings are made of nitrile rubber-organic small molecule hybrid composite material, exhibiting excellent damping performance. This invention utilizes the outer clamp to provide nonlinear constraint stiffness and nonlinear constraint damping to achieve nonlinear vibration reduction, enabling wide-frequency vibration reduction and effectively improving the vibration reduction performance of traditional single-layer clamps. This device is easy to manufacture and install, employs a nonlinear passive vibration control strategy, and achieves high efficiency at low cost.
