Abstract

The invention provides a valve control type semi-active oscillating damper. The valve control type semi-active oscillating damper comprises an oil cylinder component and an extra-cylinder component which is positioned on the outer side of the oil cylinder component, wherein the oil cylinder component comprises a guide bearing, an oil cylinder and a bottom valve seat which are fixedly connected with one another in turn; an oil storage tank is arranged outside the oil cylinder, and a piston and a piston rod are arranged in the oil cylinder; the extra-cylinder component comprises a first switching valve, a second switching valve, a two-position three-way valve, a proportional overflow valve, a throttling valve, a throttling overflow valve, a body acceleration sensor and a controller; the body acceleration sensor is used for detecting the acceleration of a body, outputting a signal and transmitting the signal to the controller; and the controller is used for controlling the energization and de-energization states of the first switching valve, the second switching valve and the two-position three-way valve, and controlling the current intensity of the proportional overflow valve at the same time. The valve control type semi-active oscillating damper is simple in structure, can make real-time responses and provide a continuously adjustable damping force according to the state of a train during operation, and can be simply and reliably controlled.

Description

technical field [0001] The invention belongs to the field of construction machinery for vehicles, and in particular relates to a valve-controlled semi-active shock absorber. Background technique [0002] As high-speed EMUs are running one after another, the lateral vibration of vehicles is an important factor affecting the ride comfort of high-speed trains. However, the damping of traditional passive shock absorbers is determined through initial design and optimization methods. Once selected, it cannot be adjusted during vehicle operation. Moreover, when the vibration velocity direction of the vehicle body is inconsistent with the relative velocity direction of the piston of the passive shock absorber, the damping force provided by the passive shock absorber will aggravate the vibration of the vehicle body and deteriorate the ride comfort. [0003] The control theory of the semi-active shock absorber between the railway vehicle body and the bogie frame is known as the skyho...
