Experimental device and method for measuring mechanical property of special material in macroscale

Abstract

The invention provides an experimental device and a method for measuring a mechanical property of a special material in macroscale. The experimental device comprises an experiment running collecting system, an experiment controlling and processing system, an experiment operation recording system, and an experiment supporting and protecting system, wherein the experiment controlling and processing system is used for controlling the experiment running collecting system, the experiment operation recording system is used for recording data collected by the experiment running collecting system, and the experiment supporting and protecting system is used for integrating, fixing and protecting the experiment running collecting system, the experiment controlling and processing system and the experiment operation recording system; the measuring method comprises the following steps of: using a servo motor to drive a linear moving guide rail so as to accurately control a moving speed of a sample, and synchronously reading a displacement and speed real-time monitoring value, on the other hand, a pull-press bidirectional sensor is adopted to directly measure mechanical data to obtain important mechanical parameters like Young modulus; the device realizes simplicity of mechanical property data of the special material, convenience of control, repeatability of procedures and reliability of results in an accurate collection process.
