Oil pressure vibration reduction piston valve system, computer device and readable storage medium

Abstract

The invention discloses an oil pressure vibration reduction piston valve system, a computer device and a readable storage medium, and relates to the technical field of vibration reduction piston valves. The oil pressure of a damping adjusting valve, the oil pressure of a piston one-way valve, a spring stiffness signal, the oil pressure of a bottom valve and a pre-tightening force signal of the oilpressure vibration reduction piston valve system are collected; a convolutional neural network is used for training and testing sample data, a wide residual network model is introduced, and filteringcompromise of high-frequency noise signals and low-frequency characteristic signals of the oil pressure of the damping adjusting valve, the oil pressure of the piston one-way valve, the spring stiffness signal, the oil pressure of the bottom valve and the pre-tightening force signal data is achieved by widening a convolution kernel; and classical time domain statistical characteristics, frequencydomain characteristics and the like of various signals are extracted, and faults of the oil pressure vibration reduction piston valve system are classified and identified. According to the oil pressure vibration reduction piston valve system, the computer device and the readable storage medium, the problem that in the prior art, in the long-term operation of an oil pressure vibration reduction piston valve system for a high-speed motor car, whether the work of all structures is effectively implemented or not or possible fault early warning is lack of effective detection cannot be solved.

Description

technical field [0001] The disclosure of the present invention relates to the technical field of damping piston valves, in particular to an oil pressure damping piston valve system, computer equipment, and a readable storage medium. Background technique [0002] At present, the hydraulic shock absorber is an important part of the rail vehicle and has a high technical content. The force value in the direction of tension and compression in its work is mainly through four or six sets of springs in the shock absorber piston. Pre-tightening is generated. The pre-tightening method is usually to manually pre-tighten the adjustment screw and then use the spring testing machine to detect the spring pre-tightening force. Adjust according to the deviation between the measurement result and the process requirements. The adjustment method is to rotate the adjustment screw again and then test the cycle , until the spring is adjusted to the qualified preload range, there is a high requirem...

Problems solved by technology

[0038] Although the state information of each mode can reflect the fault information of the oil pressure damping piston valve system to a certain extent, its universality and robustness still need to be improved.
