Abstract

The invention provides a novel vibration control device with vibration isolation and absorption functions. The novel vibration control device comprises an outer corrugated pipe, an inner corrugated pipe, an upper end plate, a lower end plate and a mass block; the upper end plate and the lower end plate are in bolted connection with mechanical equipment and an installation base by the aid of through holes; the outer corrugated pipe is fixedly connected with the upper end plate and the lower end plate in a welded manner and realizes effects of a vibration isolator; and two ends of the inner corrugated pipe are respectively fixedly connected with an inner cover and the mass block, and the axial rigidity of the inner corrugated pipe and the mass of the mass block are adjusted, so that effects of a vibration absorber can be realized. Accordingly, the novel vibration control device has the vibration isolation and power vibration absorption functions, has the advantage of compact structure, and can easily solve the problem of difficulty in controlling vibration of mechanical equipment which is arranged at a small spatial position and is incapable of being simultaneously provided with vibration isolation and absorption devices.

Description

technical field [0001] The invention relates to a vibration control device with both vibration isolation and vibration absorption functions, and belongs to the technical field of vibration isolation and vibration absorption. Background technique [0002] In the field of engineering and academia, vibration isolators and vibration absorbers have been regarded as two different vibration control devices. The working mechanism of the vibration isolator is to reduce the dynamic coupling between the vibration source and the vibration-isolated object, reduce the transmission of bad vibration to the protected object or from the object to achieve the purpose of isolating vibration transmission. The rubber vibration isolator of the seat, the airbag vibration isolator used for the vibration isolation of ship mechanical equipment, etc.; the principle of the vibration absorber is to use it to resonate, so that the elastic restoring force on the vibration absorber spring can balance the ex...
