Embodiment Construction

[0026] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings. For those skilled in the art, the above objects, features and advantages of the present invention will be apparent from the detailed description of the present invention.

[0027] refer to figure 1 , is a schematic diagram of the overall structure of a dynamic impact loading test bench according to a specific embodiment of the present invention. As shown in the figure, the dynamic impact loading test bench 100 includes an impact unit, a tension spring unit, a lifting unit and a specimen carrying platform carried on a fixed frame.

[0028] exist figure 1 Among them, the impact unit is a T-shaped heavy hammer, which includes a hammer body 5 forming a body and a hammer head 14 forming a striking part. The hammer body 5 is coated with a nylon sleeve, which is used to reduce the friction with the "I"-shaped adjustment horizontal plate 6...

Abstract

The invention discloses dynamic impact loading test bed and a test system thereof. The dynamic impact loading test bed comprises an impact unit, a lifting unit and a test piece plummer, wherein the impact unit is carried on a fixed rack and is connected with a tension spring unit; and the tension spring unit can exert an elastic restoring force on the impact unit. The dynamic impact loading test system comprises the dynamic impact loading test bed and tests the mechanical property of a test piece to be tested by connecting with a computer. The dynamic impact loading test bed and the system exert extra downward elastic restoring force on the impact unit by the tension spring unit, can still obtain higher impact loading speed under the precondition of realizing device miniaturization and has the functions and advantages of high energy conversion rate, little noise pollution, stable emission, easy speed regulation, convenient test repetition, and the like.

Description

technical field [0001] The invention relates to test equipment in the technical field of structural deformation and mechanical experiments, in particular to a dynamic impact loading test bench and a test system thereof. Background technique [0002] In engineering practical applications, many engineering materials and structures are subjected to impact loads, and the materials subjected to these loads deform at high strain rates. A large number of experimental results show that under different strain rates, the mechanical properties of materials are often different. Therefore, the dynamic mechanical properties of materials are of great significance to the safety and reliability design of engineering structures. [0003] At present, the testing equipment often used in the study of the mechanical properties of materials under high strain rates is the drop weight testing machine. The basic principle is: a heavy hammer is released from a high place, and the heavy hammer falls ...
