A sudden load test device

Abstract

The invention discloses a suddenly applied load testing device. The suddenly applied load testing device comprises a support, a tension sensor, a cable force adjusting device, a cable breaking device, a gravity loading device and a controller, wherein the upper end of the cable force adjusting device is connected with the top of the support; an output end of the cable force adjusting device is connected with the upper end of the tension sensor through a rope; the lower end of the tension sensor is connected with the upper end of the cable breaking device; the lower end of the cable breaking device is connected with the upper end of the gravity loading device; the lower end surface of the gravity loading device is in contact with the upper surface of a test piece; an output end of the tension sensor is connected with an input end of the controller; and an output end of the controller is connected with a control end of the cable force adjusting device. By the device, instant compression strength of the test piece can be quantitatively analyzed.

Description

Technical field [0001] The invention belongs to the field of test performance detection equipment, and relates to a load test device, in particular to a sudden load test device. Background technique [0002] To measure the dynamic characteristics and ultimate bearing capacity of the test piece when a sudden load is applied, the measurement process in the prior art is: first hoist the heavy object, where the heavy object is facing the specimen, and then drop the heavy object onto the specimen On the above, the dynamic characteristics and ultimate bearing capacity of the specimen under sudden load are measured. However, there is a non-linear relationship between the effect of the weight on the specimen and the height and weight of the weight, so the weight cannot be accurately measured. The force exerted by the object on the test piece can not accurately measure the input energy of the test piece, and thus cannot measure the dynamic characteristics and ultimate bearing capacity of ...

[0002] To measure the dynamic characteristics and ultimate bearing capacity of the test piece under sudden load, the measurement process in the prior art is: first lift the heavy object, wherein the heavy object is facing the test piece, and then drop the heavy object to the test piece In this way, the measurement of the dynamic characteristics and ultimate bearing capacity of the specimen under sudden load is realized. However, there is a nonlinear relationship between the effect of the heavy object on the specimen and the height and weight of the heavy object, so the weight cannot be accurately measured. The force of the object on the specimen, so that the energy input by the specimen cannot be accurately measured, and the dynamic characteristics and ultimate bearing capacity of the specimen under sudden load cannot be measured.
