Problems solved by technology

[0002] In the hydraulic inertial element, the liquid rotates and flows in the return pipe, which not only generates inertial force, but also generates damping force. In order to obtain a larger inertial force, the cross section of the return pipe is usually reduced, but the damping force will increase significantly. Large, covering the effect of inertial force, the coupling effect of this inertial force and damping force greatly limits the application of hydraulic inertial components

Abstract

The invention provides a novel hydraulic type inerter damping device, a piston is in clearance fit with a hydraulic cylinder, through holes are formed in the piston, and when the damping device works, part of working liquid flows into the working space on the other side of the piston through the clearance between the piston and the hydraulic cylinder and the through hole in the piston; non-linear damping force with a low speed index is generated by flowing of the working liquid, overlarge damping output can be limited, and the device is effectively protected. A ball and a plugging ball are arranged in a spiral return pipe communicated with the hydraulic cylinder, the other part of liquid rotates along the spiral return pipe, the ball and the plugging ball roll in a reciprocating mode under the action of pressure difference, and the mass amplification effect can be achieved through the conversion mode from linear motion of the piston to rotating motion of working liquid. The inertia force is improved, meanwhile, the coupling effect of the damping force and the inertia force in the spiral return pipe is weakened, the damping performance is improved, and dimethyl silicone oil is adopted as working liquid so that the damping output level can be increased.

Description

technical field [0001] The invention relates to the technical field of building damping control, in particular to a novel hydraulic inertial capacity damping device. Background technique [0002] In the hydraulic inertial element, the liquid rotates and flows in the return pipe, which not only generates inertial force, but also generates damping force. In order to obtain a larger inertial force, the cross section of the return pipe is usually reduced, but the damping force will increase significantly. The coupling effect of this inertial force and damping force greatly limits the application of hydraulic inertial components. Contents of the invention [0003] The purpose of the present invention is to provide a new type of hydraulic inertial shock absorber, which can increase the inertial force and reduce the damping force in the return pipe by filling steel balls in the return pipe, thus weakening the inertia and damping. coupling effect. [0004] The invention provides...
