Abstract

The invention discloses a movable vibration exciter for simulating a train load and a loading method thereof. The movable vibration exciter comprises a rail mechanism, a traction device and a vibration device, the traction device and the vibration device are both movably arranged on the rail mechanism, the rear end of the traction device is hinged to the front end of the vibration device, the traction device is used for driving the vibration device to move on the rail mechanism, and the vibration device is used for generating variable-frequency excitation force to the rail mechanism. The traction device and the vibration device are arranged on the rail mechanism, the vibration device is driven by the traction device to move on the rail mechanism, variable-frequency excitation force is generated on the rail mechanism in the moving process of the vibration device, the loading process of the vibration device can effectively simulate the real train load, and the influence of the train loadon a roadbed is analyzed; guidance can be provided for engineering construction according to dynamic response result feedback of the roadbed, the train load can be well simulated, the difficulty is low, the simulation trueness is high, and the simulation is closer to the actual situation.

Description

technical field [0001] The invention belongs to the technical field of high-speed railway engineering, in particular to a mobile vibration exciter for simulating train load and a loading method thereof. Background technique [0002] Compared with traditional road, waterway and air transportation, high-speed railway has outstanding advantages in terms of large capacity, high speed, low energy consumption and safety. The vigorous development of high-speed railway marks that traditional railway transportation has entered a new era . Up to now, the total mileage of China's high-speed railways has exceeded 35,000 kilometers, accounting for seven tenths of the world's total mileage, ranking first in the world. In the foreseeable future, my country's high-speed railway construction will continue to maintain rapid development, and the next few decades will be a golden period for high-speed railway construction. [0003] Safety is an issue that needs to be focused on in the constru...
