Problems solved by technology

This structure is simple, but there are the following defects: ① one end of the double rod is the force output end of the inerter, but the other end is only to occupy the volume in the cylinder, but it needs to be reserved for the volume of the piston rod in engineering design. Leave space, increase the axial dimension
②The longer the external pipeline, the greater the inertia coefficient of the fluid inerter, but because the pipeline is arranged in a spiral shape, the parasitic damping force is too large, and the mechanical properties of the inertial force are difficult to show

Abstract

The invention relates to the technical field of vibration reduction and vibration isolation, and discloses a double-barrel type fluid inerter device. The double-barrel type fluid inerter device comprises a first hydraulic cylinder and a second hydraulic cylinder which are connected, each of the first hydraulic cylinder and the second hydraulic cylinder comprises a cylinder barrel, a piston movably arranged in the cylinder barrel and a piston rod connected with the piston, and a main oil cavity and an annular cavity are located in each cylinder barrel and located on the two sides of the piston; the main oil cavities of the first hydraulic cylinder and the second hydraulic cylinder are communicated through a first pipeline, and the annular cavities of the first hydraulic cylinder and the second hydraulic cylinder are communicated through a second pipeline; and the second hydraulic cylinder is connected with an external vibration system. According to the device, two single-piston-rod hydraulic cylinders, namely the first hydraulic cylinder and the second hydraulic cylinder are adopted, the main oil cavities of the two hydraulic cylinders communicate, the annular cavities of the two hydraulic cylinders communicate, and the second hydraulic cylinder is connected with the external vibration system, so that the axial size of a fluid inerter can be greatly reduced, space arrangement is facilitated, the installation convenience is improved, parasitic damping force can be effectively reduced, and inertia force is increased.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and vibration isolation, and more specifically relates to a double-tube fluid inertial device. Background technique [0002] In 2002, Smith of Cambridge University proposed the concept of Inerter, and thus constructed a new theoretical system of vibration isolation of "Inerter-Spring-Damping". Inerters help to solve common problems in the field of vibration and noise reduction. The performance is as follows: ① The inerter has excellent vibration reduction performance in the field of vehicle suspension, and can greatly increase the average speed of multi-axle off-road vehicles; ② In the field of vibration reduction when super high-rise buildings are hit by earthquakes or typhoons, the inerter has Potential to replace the mass damper weighing several hundred tons, and reduce the weight to less than 10 tons, greatly saving consumables; ③The inertia is also being extended to other technic...
