Description

Technical Field

[0001] The utility model relates to the technical field of damping devices, in particular to an organosilicon acrylate composite rubber spring mass damping device for a chimney. Background Art

[0002] In the industrial chimney structure, the damper is a very important device for structural safety. During the use of the damper, the pendulum length of the pendulum mass damper is not easy to adjust and the mass change is difficult, which is a very big disadvantage. At the same time, the damping material will also have different loss modulus and hysteresis loss due to different effective damping temperature ranges. A Chinese patent discloses a "chimney shock absorbing device", whose application number is "CN202122577102.8", which includes a mass ring suspended on the outside of the chimney, a flexible connector for hoisting the mass ring, and at least three damping members arranged on the outside of the chimney; the damping member faces the central axis of the chimney, and both ends of the damping member are provided with universal joints to connect the mass ring and the chimney respectively. Using the technical solution of this application, when the chimney vibrates, the mass ring remains stationary under the action of inertia, and the mass ring cooperates with the damping member to generate a damping force on the chimney in the opposite direction of the vibration. The damping force acts on the outer wall of the chimney toward the central axis of the chimney, which can effectively hinder the vibration of the chimney, thereby playing a vibration reduction role. The damping element of the present application is an adjustable magnetorheological damper, and the shock absorbing device can automatically adjust the damping force according to the vibration intensity of the chimney to effectively deal with the different degrees of vibration of the chimney, and its shock absorbing effect is better. However, the pendulum length of the damper is not easy to adjust, and it is difficult to change the mass, which is not conducive to the control of the device. Utility Model Content
