Lateral shock excitation and force measurement device for train

Abstract

The invention provides a lateral shock excitation and force measurement device for a train, and the device comprises a shock excitation device for providing an earthquake action, a bridge-train model for research, and a force measurement system, wherein the measurement system comprises a force measurement sensor. The shock excitation device comprises a vibration power source, a power loader, a fixed pedestal, a sliding rail group, and a vibrating platform seat. The bridge-train model comprises a high pier model, a simply-supported box girder model, a rail model, and a train model. The train model comprises a train body, a wheel pair, a wheel pair chassis and a connecting rod. A force measurement sensor is disposed between the train body and the wheel pair chassis. According to the technical scheme of the invention, the beneficial effects of the invention are that the device is simple in overall structure and is convenient to operate; the device can precisely obtain an overlapping action force from crosswind and lateral shock excitation on a moving train through the design of the shock excitation device and the train model; the device can achieve the simulation of a process that the bridge-train in an operating state in an actual project are suffered from strong wind and earthquake, and provides basis for the guarantee of the operation safety of the train.

Description

technical field

[0001] The invention relates to the technical field of locomotives, in particular to a train transverse excitation and force measuring device. Background technique

[0002] The rapid development of high-speed railway is an important manifestation of national economic development and national strength enhancement. On July 20, 2016, the National Development and Reform Commission issued a notice on printing and distributing the "Medium and Long-term Railway Network Planning". According to the plan, by 2025, the scale of my country's railway network will reach 175,000 kilometers, of which the high-speed railway will reach 38,000 kilometers. The main passages of high-speed railways will form a pattern of "eight horizontal and eight vertical", forming a high-speed network connecting major cities in China. As a result, the possibility of high-speed trains passing through strong wind areas and earthquake-prone areas is greatly increased, and the probability of multi...
