Traffic load simulation device

Abstract

The invention relates to the technical field of indoor model test devices, in particular to a traffic load simulation device. Comprising a model box, a door-shaped bracket, a vibration mechanism and a roller mechanism, an upper cross beam is arranged at the upper end of the door-shaped bracket; the vibration mechanism, the roller mechanism and the model box are sequentially arranged below the door-shaped bracket from top to bottom; the vibrating mechanism comprises a vibrating motor, a pair of cross rods, a connecting rod, a mounting seat, an upper pressing plate and a lower pressing plate; the roller mechanism comprises a screw motor, a screw, a jack and a support frame; an upright short cylindrical table is fixedly arranged at the upper end of the mounting connecting plate, the lower end of the jack is fixed with the upper end of the short cylindrical table, and the upper end of the jack is in rolling contact with the small roller through a horizontal plate; the screw rod horizontally penetrates through the short cylindrical table and is in threaded connection with the screw rod, the screw rod motor is started to enable the screw rod to rotate, and the short cylindrical table moves on the screw rod. Therefore, the vibration mechanism can simulate the vibration of the vehicle, and the roller mechanism can effectively simulate the running load under the real condition.

Description

technical field [0001] The invention relates to the technical field of indoor model test devices, in particular to a vehicle load simulation device. Background technique [0002] Research in the direction of geotechnical engineering often involves indoor model tests. The indoor model reduces the actual structure according to a certain similarity ratio, and related research can be completed indoors. Model tests are widely used by researchers because of their time-saving, low cost, high practicability, and their ability to reflect various aspects of the actual structure. At present, most of the indoor model tests involved in the geotechnical direction are static tests, which refer to applying a load whose magnitude and action point do not change with time on the test model, or loading a cyclic load to study the stress-strain characteristics of the representative structure. . [0003] However, the study of geotechnical engineering structures is far from enough to remain stati...
