Wave-shaped pipe surrounding type gas inerter

Abstract

The invention discloses a wave-shaped pipe surrounding type gas inerter which comprises a cylindrical tank, a wave-shaped pipeline, a piston, a piston rod, a baffle and a horizontal partition plate. The horizontal partition plate is arranged in the cylindrical tank. The horizontal partition plate divides the cylindrical tank into an upper cavity and a lower cavity which are independent and do notcommunicate. The cavity located in the upper portion is an air cylinder, and the other cavity is a stroke chamber. The piston is fixed to the piston rod. The baffle is fixed to the bottom face of thepiston rod. The upper end of the piston rod extends out of the center of the top face of the air cylinder, the piston is located on the air cylinder, the baffle is located in the stroke chamber, and the wave-shaped pipeline is fixed to the outer wall of the cylindrical tank. Two pipe openings of the wave-shaped pipeline communicate with the air cylinder. A section of liquid is contained in the wave-shaped pipeline, and the liquid of this section can only flow in the wave-shaped pipeline back and forth, and cannot enter the air cylinder. When the inerter works, the piston moves in the air cylinder back and forth. The baffle has a function of restraining the relative displacement amount of two end points, and the situation that the liquid in the wave-shaped pipe enters the air cylinder, theinerter cannot work normally can be prevented.

Description

technical field [0001] The invention belongs to an energy storage element, in particular to a corrugated tube surrounding type gas inertial capacity. Background technique [0002] Inertia is a mechanical energy storage element, characterized by the force acting on two endpoints is proportional to the relative acceleration between the two endpoints, the ratio is called inertia. As a kind of passive mechanical components, inertial components, springs and dampers can constitute more abundant passive mechanical structures compared with mass blocks. Inerter is the complete mechanical dual of spring and has a wide range of application backgrounds. Its main functions include vibration absorption, suspension design, and alternative mass. In the field of vehicle design, inertia can be used for the vibration reduction of aircraft landing gear, and can be used in the suspension system of various vehicles such as trains and automobiles to improve suspension performance, thereby improvi...

AI Technical Summary

Problems solved by technology

[0008] (3) There is kinetic energy loss at the connection between the spiral tube and the hydraulic cylinder

[0009] (4) The work done by the force F cannot be completely converted into the kinetic energy of the liquid movement in the spiral pipe, and part of it must be converted into the kinetic energy of the liquid in the hydraulic cylinder

[0010] These shortcomings lead to a high degree of non-linearity in the inertial capacity of the spiral liquid, which is not suitable for situations where the linearity of the inertial capacity is required to be high.
