Abstract

The invention provides an intelligent control method for the stiffness of a pivot arm node, which belongs to the technical field of pivot arm nodes. The magneto-rheological elastomer layer between the mandrel and the jacket and the excitation coil suitable for providing strength adjustment for it, the control method includes: obtaining the lateral displacement parameter of the wheel set and the lateral displacement parameter of the frame; according to the lateral displacement parameter of the wheel set parameters and the lateral displacement parameters of the frame, the lateral relative velocity parameters of the primary suspension of the locomotive are calculated; according to the lateral displacement parameters of the frame and the lateral relative velocity parameters of the primary suspension of the locomotive, the excitation coil is started. The intelligent control method of the joint stiffness of the pivot arm provided by the invention aims to solve the problem of how to intelligently realize the automatic adjustment of the joint stiffness of the pivot arm according to the motion state of the train.

Description

technical field [0001] The invention belongs to the technical field of pivoting arm joints, and more specifically relates to an intelligent control method for the stiffness of pivoting arm joints. Background technique [0002] The axle box structure is the movable joint connecting the frame and the wheel set on the rail vehicle. In addition to transmitting forces and vibrations in various directions, the axle box structure must also ensure that the wheel set can adapt to the track conditions and move up and down and laterally relative to the frame. Axle box positioning is also wheel set positioning, that is, restricting the mutual position between the wheel set axle box and the frame. The load is transmitted and distributed to the wheelset; the wheelset rotates flexibly, and the bogie passes the curve smoothly; the stable inertia of the car body is used to restrain and reduce the lateral swing of the axle box. Therefore, the positioning of the axle box plays a decisive role...
