Abstract

The invention provides a plate rolling device based on particle damping vibration attenuation and a damping vibration attenuation design method thereof.The plate rolling device comprises a main body structure and a hollow supporting structure, and the supporting structure is used for supporting the main body structure; the supporting structure is filled with a plurality of damping particles, the damping particles are divided into metal particles and non-metal particles according to materials, and the particle size of at least part of the metal particles is different from the particle size of other metal particles. And the particle sizes of at least part of the nonmetal particles are different from those of other nonmetal particles. The hollow structure in the supporting structure is effectively utilized, the inner cavity of the supporting structure is filled with the metal particles and the non-metal particles, damping of the plate rolling device is increased through the damping particles with different particle sizes, the anti-vibration capacity of the plate rolling device is improved, vibration of the plate rolling device is restrained accordingly, and the equipment machining capacity and quality are improved; and the service lives of equipment parts and the whole machine are prolonged.

Description

technical field [0001] The invention belongs to the technical field of plate rolling device vibration reduction, and relates to a plate rolling device based on particle damping and vibration reduction and a damping and vibration reduction design method thereof. Background technique [0002] The plate rolling device is a general forming equipment that bends metal sheets into cylinders, cones, curved surfaces or other shapes. According to the principle of three points forming a circle, the relative position change and rotational movement of the work rolls are used to produce continuous plastic deformation of the plate to obtain a predetermined shape of the workpiece. The roller plate rolling device can not only roll plates, but also bend various profiles. It is an indispensable general-purpose process equipment and belongs to the machinery manufacturing industry. [0003] There are a series of system vibrations in the plate rolling device during the plate rolling process, inc...
