Abstract

The invention relates to a material rheological model analyzer. The analyzer comprises a sample room arranged in an environment temperature control box, a test material, a slice and a thermistor are arranged in the sample room; the slice is connected with a steel band, the steel band traverses through a guide wheel and is connected with an upper metal block in a magnetorheological fluid, and a lower metal block in the magnetorheological fluid is sequentially connected with a tension sensor, a miniature motor, a digital analog converter and a computer through the steel band; the steel band between the slice and the guide wheel is provided with a balancing counterweight, and the steel band between the guide wheel and the upper metal block is provided with a light attenuator; and a He-Ne laser is arranged under the guide wheel, a laser signal emitted by the He-N3 laser goes through the light attenuator and then is received by a CCD charge coupler, and the CCD charge coupler is sequentially connected with a signal amplifier, the digital analog converter and the computer. The invention also discloses a material rheological model establishing method. The material rheological model is established to predicate the rheological characteristics of a material under different conditions.

Description

technical field [0001] The invention belongs to the field of material rheology, and in particular relates to a material rheological model analyzer and a method for establishing a material rheological model. Background technique [0002] Rheometer is used to test the rheological properties of materials to guide the development, processing and application of materials. Existing rheometers include: rotational rheometer, capillary rheometer, dynamic shear rheometer, and bending beam rheometer. The rotational rheometer is used to test the viscosity of the liquid at a constant temperature. By testing the viscosity of the liquid at different temperatures, the viscosity-temperature characteristics of the material can be obtained; the capillary rheometer is used to test the viscosity of the polymer melt at a constant temperature, which can reflect The high-temperature rheological properties of polymers; the dynamic shear rheometer is mainly used to test the viscoelastic properties o...
