Embodiment Construction

[0022] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0023] Generally speaking, the frequency, amplitude, strain rate, and carried energy of the stress wave will be significantly reduced when the power sources such as blasting and impact are from near to far. In order to obtain accurate dynamic response and parameter results of coal and rock, an excitation device in the corresponding frequency range should be used to excite and test coal and rock materials.

[0024] At the mine scale, the propagation distances of the above-mentioned power sources mostly do not ex...

Abstract

The invention provides impact test equipment which comprises an impact warhead, the elasticity modulus of the impact warhead is determined according to target frequency, and the elasticity modulus andthe target frequency are in positive correlation. According to the impact test equipment provided by the invention, the material with the proper elasticity modulus is selected according to the targetfrequency to customize the impact warhead, the required main frequency component can be output, and the problem that the main frequency component output by the impact test equipment does not correspond to the real underground energy wave main frequency component in the frequency domain range is solved. Impact test equipment with proper frequency is customized, so that serious theoretical defectsof the impact test equipment are avoided.

Description

technical field [0001] The present application relates to the technical field of impact testing, in particular to an impact testing equipment. Background technique [0002] In related technologies, the main frequency component output by the impact test equipment does not correspond to the main frequency component of the real energy wave downhole in the frequency domain, and the coal-rock medium under test has different dynamic response and dynamics under dynamic loads of different frequencies. The mechanical performances such as parameters and failure modes are completely different, which makes the traditional impact test equipment have serious theoretical defects. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, one purpose of this application is to propose a kind of impact test equipment, to solve the problem that the main frequency component output ...
