Problems solved by technology

[0002] When the standard EMU is running on the line, it is required to have good lateral stability. In the range of low speed to maximum speed, no hunting instability is allowed. If severe hunting instability occurs, a large lateral wheel-rail force will be generated. , causing damage to the line, overheating or damage to the axle bearing, and even a derailment accident, which seriously affects the operation safety

Abstract

A transverse buckling instability detecting device used for a standard D-series high-speed train includes a transverse acceleration sensor, a signal cable, a cable connector and a cable sheath tube. The transverse acceleration sensor is in communicational connection with one end of the cable connector through the signal cable. The periphery of the signal cable is provided with the cable sheath tube. The other end of the cable connector is in communicational connection with a BIDS (Buckling Instability Detection System). The invention has beneficial effects that a modularized circuit and structural design idea is adopted; simpleness and reliability are achieved; and batch production is promoted.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a lateral instability detection device for a standard train set. Background technique [0002] When the standard EMU is running on the line, it is required to have good lateral stability. In the range of low speed to maximum speed, no hunting instability is allowed. If severe hunting instability occurs, a large lateral wheel-rail force will be generated. , causing damage to the line, overheating or damage to the axle bearings, and even derailment accidents, which seriously affect the safety of operation. Therefore, the prevention of snaking instability is one of the issues that urgently need attention in the research of high-speed railway vehicles. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provides a lateral instability detection device for standard EMUs, which is specifically realized by the following t...
