Abstract

The invention discloses a soft material mechanical performance measurement apparatus and a method thereof. The apparatus comprises a voice coil motor, a controller, a computer, a translation stage and a CCD camera, the voice coil motor is arranged on a rack and is controlled by the controller, the voice coil motor comprises a grid ruler, a force sensor and a main shaft which are arranged in the voice coil motor, the controller is connected with the computer, and the controller drives the voice coil motor to linearly move along a vertical direction according to an instruction sent by the computer, and sends the displacement and load data obtained by the grid ruler and the force sensor to the computer in order to obtain the load-displacement relationship of a soft material to be measured; and the translation stage is arranged under the voice coil motor and is used for disposing the soft material, one side of the soft material is provided with the CCD camera, and the CCD camera is used for shooting the deformation image of the soft material before and after pressurization and transmitting the deformation image to the computer. The method uses the measurement apparatus to measure. The apparatus and the method have the advantages of compact structure, complete functions, high measurement precision and wide measurement range.

Description

technical field

[0001] The invention belongs to the field of testing the mechanical properties of soft materials, and more particularly relates to a device and method for measuring the mechanical properties of soft materials. Background technique

[0002] Soft material is a special kind of substance between solid and ideal fluid. It is generally composed of macromolecules or molecular clusters. It has two remarkable characteristics of softness and complexity. Soft materials mainly include rubber, biological tissue and liquid crystals, which are closely related to our daily life. Compared with general engineering materials, soft materials have very unique and excellent properties, such as rubber has corrosion resistance, flexibility, wear resistance, heat insulation Insulation and other advantages, it has a wide application background in the fields of aerospace, biomaterials, industrial engineering and medicine. Therefore, the testing of soft materials is very important. Aft...
