Abstract

The present invention discloses a portable tail vertical excitation device. The portable tail vertical excitation device comprises a control system, a reaction system and a loading device. The loading device is connected with the control system and the reaction system; the loading device includes a drop hammer, a first balancing weight, a power device and second balancing weights; the first balancing weight is connected with the power device through wire ropes; two pulleys are respectively arranged at two side surfaces of the first balancing weight at intervals; a plurality of second balancing weights is arranged between the drop hammer and the first balancing weight, and a circular hole is arranged at the center of the second balancing weights and configured to a sensor; the drop hammer, the second balancing weights and the first balancing weight are fixedly connected in order; and the sensor and the control system are connected. The portable tail vertical excitation device is easy to carry, convenient for operation, reasonable in size of the test device and small in weight.

Description

technical field [0001] The invention belongs to the technical field of railway engineering and relates to a portable rail vertical vibration device. Background technique [0002] In today's society, with the rapid development of my country's economy, my country's transportation infrastructure construction has entered a period of great development, and the operating mileage of trains has reached an unprecedented level. Therefore, it is necessary to carry out experimental research on railway line dynamics, especially on the excitation effect of track structures. is essential. The most critical technical difficulty is how to accurately simulate the characteristics of the train load. After searching the relevant patent and scientific literature databases, no portable loading device with real wheel-rail geometry has been found yet. In field in situ testing, simulating real wheel-rail geometry is crucial for test accuracy. Contents of the invention [0003] In order to overcome...
