A structure model impact loading device

Abstract

The present invention belongs to the technical field of structure model impact loading, and especially relates to a structure model impact loading device. The device comprises a main frame, an impactmodule, a regulation seat and a displacement regulation module. The regulation seat comprises vertical plates and connection rods, installation holes penetrate the plate surfaces of the vertical plates, transmission rods penetrate the installation holes, the four transmission rods are distributed at four corner ends of the vertical plates in a square plate shape; an impact module is a pendulum bob; the device comprises a horizontal sliding support, a sliding rod of the horizontal sliding support is sleeved with a rotating sleeve, the horizontal sliding support is provided with a horizontal expansion valve, and the rotation sleeve penetrates the horizontal expansion valve to control the rotation sleeve to perform displacement motion in a horizontal direction along the sliding rod; a liftingrod is extended downwards at the outer wall of the rotation sleeve in a vertical direction, a vertical expansion valve is employed between the lifting rods and a bob rod of the pendulum bob to control the lifting rods and the bob rod to move to each other in opposite directions and move away from each other in opposite directions; and the pendulum bob controls the swing amplitude through a stay cord. The structure model impact loading device can achieve the purpose of single-point or multi-point impact at any position of a structure model.

Description

Technical field [0001] The invention belongs to the technical field of structural model impact loading, and in particular relates to a structural model impact loading device. Background technique [0002] With the development of social science and technology, many application components often need to undergo modeling and structural model impact loading experiments to verify their structural reliability before being put into actual production. The correct evaluation of the structural reliability of the structural model must be based on accurate and comprehensive test data. Although there are more and more experimental studies on impact loading of structural models, the structure of the loading device is relatively single and the application is relatively poor. Therefore, on the one hand, the function of the loading device is not fully used, and the accuracy of data measurement is relatively high. Poor; on the other hand, it also leads to the poor applicability of the current load...

Problems solved by technology

Although there are more and more researches on impact loading experiments of structural models, the structure of the loading device is relatively simple and the application flexibility is poor, so on the one hand, the function of the loading device is not fully used, and the data measurement accuracy is relatively low. On the other hand, it also leads to the poor applicability of the current loading device, the narrow scope of application, and the inability to effectively test and simulate arbitrary impact load loading. caused great difficulty
