Intermittent rib type composite vibration damping energy dissipator and manufacturing method thereof

Abstract

The invention discloses an intermittent rib-type composite vibration-damping energy dissipator, comprising an upper panel and a lower panel, a plurality of composite vibration-damping structural members are arranged between the upper panel and the lower panel; the composite vibration-damping structural member It includes several energy-dissipating vibration-damping mass structural members and several wedge-tip vibration-damping support structural members, wherein the arrangement of the energy-consuming vibration-damping mass structural members and the wedge-tip vibration-damping support structural member is in the form of an m×n-order A matrix, The energy dissipation and vibration damping mass structural members (2-2) are arranged at A of the A matrix ij position, i and j are both odd or even, i≤m, j≤n; the wedge-tip vibration-damping support structure (2-1) is arranged in the remaining positions of the A matrix. The invention has scientific and reasonable structure, high rigidity and good stability, and the broken rib structure has a good inhibitory effect on the isolation and attenuation of vibration energy, and is suitable for vibration isolation and vibration reduction of large-scale power equipment. The invention also discloses a manufacturing method of the discontinuous rib type composite vibration damping energy dissipator.

Description

technical field [0001] The invention relates to an intermittent rib-type composite vibration-damping energy dissipator, in particular to a discontinuous-rib-type composite vibration-damping energy dissipation device and a manufacturing method thereof, belonging to the technical field of vibration reduction. Background technique [0002] With the development of society and the advancement of science and technology, modern power equipment has higher and higher requirements for vibration and noise indicators. For large power equipment, it often produces large vibration and radiation noise during normal operation, and these power equipment need to be treated with vibration isolation and noise reduction. The anti-vibration mass block has good damping performance for high-frequency vibration waves, which can block the transmission of vibration waves to the foundation and reduce the negative effect of high-frequency vibration on the vibration isolation effect. The wedge-shaped str...

Problems solved by technology

The parabolic hole in the middle of this invention can effectively weaken the transmission of vibration, but the propagation speed of longitudinal wave is greater than that of transverse wave, so the effect of vibration reduction and energy consumption of this invention is limited, and the vertical stiffness is small
