Embodiment Construction
[0043] The present invention will be further described below in conjunction with the accompanying drawings.
[0044] as attached figure 2 As indicated, the load cell shall include at least:
[0045] 1) The measuring sensor selects the load sensor to directly measure the loading force;
[0046] 2) The measuring sensor is vertically installed on the lower end surface of the supporting mechanism of the testing machine, and the lower end surface is required to have a certain levelness;
[0047] 3) A horizontal pallet is installed on the measuring sensor so that the loading force on the material is fully loaded on the sensor.
[0048] When carrying out the loading test, the loading test shall at least include:
[0049] 1) Considering the inertia characteristics of the hydraulic drive mechanism and the response time of the measuring sensor, the designed loading time should be as long as possible and the loading process should be as slow as possible;
[0050] 2) Considering the ...

The invention discloses a material horizontal breaking detection method of a hydraulic loading testing machine. The material horizontal breaking detection method comprises a material horizontal breaking detection method and a material breaking detection algorithm. The invention also discloses a material horizontal breaking safety processing control method of a hydraulic loading testing machine. The safety processing control method comprises a material breaking safety processing measure and a safety processing control method. The provided method solves the problems that in a material testing machine test, after a material is broken, the material is loaded for a second time and damaged, explosion happens during the material secondary loading process, and the process is uncontrollable. The material loading strength, in particular, the loading strength of dangerous materials can be measured safely for the research of lab or industrial development, the measurement is controllable, and the material is not damaged. The loading strength of an energy containing material can be measured by the provided method, during the test process, the test is safe and controllable, and the material is not damaged for a second time.
Description
technical field [0001] The invention relates to a detection and control method, in particular to a material horizontal fracture detection and safety processing control method of a hydraulic loading testing machine, belonging to the technical field of mechanical equipment detection and control. Background technique [0002] The load-carrying strength of a material is an important parameter for material performance evaluation and material mechanical testing, and is directly related to the mechanical and structural properties of the material. In the military industry, some functional materials are used not only as high-energy parts of the warhead, but also as supporting structural parts of the weapon system, and their mechanical properties are directly related to the reliability and safety of the weapon system. The existing material mechanical load strength measurement generally uses material testing machines, and the industry generally uses electronic servo material testing ma...
