Problems solved by technology

However, due to the limitations of the rubber material, the dynamic stiffness of the rubber conical spring decreases with the increase of the frequency, and high-frequency dynamic softening occurs; at the same time, the damping of the rubber material is small, and the ability to dissipate vibration energy is limited.

Abstract

The invention relates to a sealing method of a liquid composite spring. The sealing method of the liquid composite spring comprises the following steps that 1, a cylindrical outer wall is arranged onthe upper portion of a mandrel in a sleeving mode, and an upper liquid chamber and a lower liquid chamber are arranged in the outer wall; and 2, a sealing member is installed at the bottom of the outer wall, and the lower liquid chamber is sealed, wherein the sealing member is made of a flexible material. According to the sealing method of the liquid composite spring, the rigid outer wall and theflexible sealing member are arranged, and the volume and the shape of the lower liquid chamber can be changed through the flexible sealing member, so that the chamber becomes a flexible chamber.

Description

technical field [0001] The invention relates to a sealing method of a liquid composite spring, which is used for the sealing method of a liquid composite spring of a vehicle, especially a rail vehicle. Background technique [0002] When the vehicle is running on the track, complex vibration phenomena are accompanied by it. Therefore, it is essential to install a spring device on the railway vehicle to attenuate mechanical vibration. Traditional rubber conical springs are easy to obtain different stiffness values ​​in the vertical, transverse and longitudinal directions, and have good nonlinear characteristics, so they can better meet the general axle box suspension requirements. However, due to the limitations of the rubber material, the dynamic stiffness of the rubber conical spring decreases with the increase of the frequency, and high-frequency dynamic softening occurs; at the same time, the damping of the rubber material is small, and the ability to dissipate vibration e...
