Abstract
The invention provides a loop accelerated loading testing system, which comprises a loading vehicle and an annular testing loop, wherein the loading vehicle comprises an upper vehicle frame, a lower vehicle frame, a guide column, a guide sleeve, a transverse movement lead screw, a driving wheel and a power mechanism; the guide column and the transverse movement lead screw which are parallel mutually are horizontally arranged at the bottom part of the upper vehicle frame; the guide sleeve is arranged on the guide column; the lower vehicle frame is arranged on the guide sleeve; a lead screw nut, the driving wheel and the power mechanism are arranged on the lower vehicle frame; the front end and the rear end of the upper vehicle frame are provided with the guide wheels, balancing wheels and side supporting wheels respectively; a third rail collector is also arranged on the upper vehicle frame; the annular testing loop comprises an annular vertical wall, crossbeams, a third rail and an annular guide rail; the inner side of the annular vertical wall is uniformly provided with a plurality of crossbeams; and the annular guide rail is arranged below the crossbeams. A driving and driven dual-wheel group rolling mode can be realized, which is consistent with the actual road rolling condition by a vehicle; by adopting the third rail mobile power supply mode, the testing speed and the testing effects are improved; and by adopting the scheme with the annular guide wheel and the guide wheels, the structure is simple, the reliability is high, and the power consumption is low.
Description
(1) Technical field [0001] The invention relates to an experimental device for accelerated loading of roads, in particular to an experimental system for accelerated loading of loops. (2) Background technology [0002] The loop acceleration loading test is a road acceleration loading test method. At present, the loop acceleration loading vehicle only has a single active wheel set to load, which is inconsistent with the actual rolling form of the vehicle on the road surface; the trolley line mobile power supply method is adopted, and the test speed is low. The effect is poor; in addition, the running guide structure of the loading vehicle is complicated, the reliability is low, and the energy consumption is large. (3) Contents of the invention [0003] The technical task of the present invention is to provide a loop accelerated loading experiment system aiming at the deficiencies of the prior art. It solves the problems of high energy consumption, low speed and inconsistenc...
