Abstract

The invention relates to a hydraulic mem-inerter device and an application thereof. The hydraulic mem-inerter device comprises a first cylinder barrel, a first piston and a spiral passage, wherein the first cylinder barrel is divided by the first piston into a left cavity and a right cavity; and the spiral passage enables the left cavity and the right cavity of the first cylinder to communicate, and the length of the spiral passage changes along with the change of the relative displacement of the first cylinder barrel and the first piston. The cylinder barrel and the piston serve as a first end point and a second end point which are independent and movable correspondingly. When used, the hydraulic mem-inerter device can be connected to a system to control mechanical force. When generating relative movement between the two end points, fluid can flow from one cavity to the other cavity of the cylinder barrel through the spiral passage, the fluid in the spiral passage has mass and can generate inertia force when flowing, and the ratio of the generated inertia force to the relative acceleration of the two end points changes along with the change of the relative displacement of the two end points. The hydraulic mem-inerter device can serve as a regulation and control valve for an inerter and a damper, can realize continuous regulation and control on the inerter and the damper, and has a wide application range.

Description

technical field

[0001] The invention relates to an inerter device and its application, in particular to a hydraulic inerter device related to inertia and displacement and its application. Background technique

[0002] The inerter is a new mechanical component, and its concept (Smith M C, "Synthesis of mechanical networks: the inerter", IEEE Transactions on Automatic Control, 47(10), 1648-1662, 2002) was proposed in 2002. An inerter has two independently movable endpoints, the relative acceleration of these two endpoints is proportional to the force exerted on the two endpoints, and one endpoint of the mass element is its center of mass, and the other endpoint is the inertial reference frame. A fixed point (mechanical ground), therefore, in the "force-current" correspondence, the mass element can only be compared to a grounded capacitor. Unlike traditional mass elements, an inerter has two independently movable endpoints, which make it unnecessary to be connected to an inert...

Embodiment Construction

[0034] The present invention will be further described below in conjunction with drawings and embodiments.

[0035] Figure 4 It is the first embodiment of the hydraulic memory container device, including a first cylinder 1, a first piston 3, and a liquid 7. The first cylinder 1 has two inner circular surfaces with different diameters, which are respectively large inner circular surfaces 5 and small inner circular surface 6, and the entire interior of the first cylinder 1 is filled with liquid 7; the outer surface of the first piston 3 cooperates with the small inner circular surface 6 of the cylinder to divide the first cylinder 1 into There are two left and right cavities, the outer surface of the first piston 3 is provided with a spiral groove 2, and the spiral passage surrounded by the spiral groove 2 and the small inner circular surface 6 connects the left and right cavities of the first cylinder 1. When the first piston 3 moves relative to the first cylinder 1, the firs...
