Mechanical test system and method for dynamically controlling surface temperature rise of material

Abstract

The invention discloses a mechanical test system for dynamically controlling the surface temperature rise of a material, which comprises a testing machine; wherein an infrared thermal imaging sensor for acquiring the temperature of an area is arranged on one side of a clamp assembly on the testing machine; when a movable clamp part on the clamp assembly circumferentially rotates from an initial position or moves up and down to an end position, the pressed deformation part of the sample is positioned in a temperature acquisition area of the infrared thermal imaging sensor; the output end of the infrared thermal imaging sensor is connected with a controller; the controller is connected with the power device, and a temperature signal collected by the infrared thermal imaging sensor can trigger the controller to send a control signal so as to adjust the power output power of the power device. The invention aims to provide the mechanical test system and method for dynamically controlling the surface temperature rise of the material, which can accurately detect the surface temperature of the sample so as to optimize the test efficiency.

Description

technical field [0001] The application relates to the technical field of testing machines, in particular to a mechanical testing system and method for dynamic control of material surface temperature rise. Background technique [0002] Mechanical testing also refers to mechanical performance testing, which mainly tests the mechanical properties of metal and non-metallic materials in terms of conventional stretching, bending, yielding, flattening, hardness, etc. Various mechanical performance criteria of metal and non-metal materials are measured through different mechanical tests. Any material will be deformed after being stressed, and will break when deformed to a certain extent. The deformation and fracture behavior of materials under external load is called mechanical behavior, which is determined by the material structure inside the material and is an inherent property of the material.
