Novel multifunctional impact fracture test device and use method thereof

Abstract

The invention discloses a novel multifunctional impact fracture test device and a use method thereof. The device comprises a movable test frame capable of ascending and descending, a combined supporting plate, a multi-form hammer, a multi-azimuth hammer movable assembly and an impact drop hammer, wherein the combined supporting plate is arranged at the bottom of the movable test frame capable of ascending and descending; a trolley is arranged on the combined supporting plate, the front part of the trolley is rotationally connected with the combined supporting plate, the rear part of the trolley is detachably connected with the front side of the movable testing frame capable of ascending and descending, and the lower part of the trolley is matched with the combined supporting plate; the multi-form hammer is movably connected with the movable test frame capable of ascending and descending through the multi-azimuth hammer movable assembly; the upper part of the multi-form hammer is matched with the lower part of the impact drop hammer, the impact drop hammer is arranged between the multi-form hammer and the multi-azimuth hammer movable assembly, the upper part of the impact drop hammer is movably connected with the multi-azimuth hammer movable assembly, and the multi-azimuth hammer movable assembly is movably connected with the upper part of the movable test frame capable of ascending and descending. The device has the advantages of being flexible, convenient to use and suitable for various working conditions.

Description

technical field [0001] The invention belongs to the technical field of test auxiliary equipment, and in particular relates to a novel multifunctional impact rupture test device and a using method. Background technique [0002] Impact test is generally a test method to determine the safety, reliability and effectiveness of military, civilian equipment, production products or laboratory test samples when they are subjected to external impact or action. At present, most of the test objects for impact rupture of plate structures are hollow plates at the bottom under the condition of simple support or fixed support at four corners or four sides. For the impact test of plate structures under more complex support conditions, the existing test equipment is still not perfect. However, this test device mainly solves the impact fracture under the condition of complete contact between the bottom surface of the test plate and the top surface of the supporting medium, and can observe and ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem that there is no contact between the test plate and the support surface of the existing impact test device, the present invention proposes a new multifunctional impact rupture test device and its use method, which can be used to study different conditions through the approximate simulation of engineering practice activities Under the influence of the impact fracture of the test sample, after recording the data, the test phenomenon can be compared with the numerical simulation phenomenon, and the basic laws can be mastered to guide engineering practice.
