Abstract

In order to test the rheological property of biological fluid more simply and more accurately test, a cone plate speed attenuation method is put forward on the base of spinning cone plate method. The cone plate is firstly driven by an eddy coil to a preset value. Then the cone plate attenuates freely under the action of a fluid viscosity force. In the system, standard viscosity oil is applied to calibrate measurement parameters and thus to eliminate systematic errors. The system employs an upper computer and a lower microprocessor and adopts broadcast communication in a master/slave manner based on RS485 serial links. The microprocessor is a LPC2131 for measuring the angular speed and the angular acceleration of the cone plate and for controlling sampling and cleaning. The upper computer is programmed with the language of Visual c++ 6.0, for data processing, data storage and data displaying. The repeatability error of the system, in which the measurement is conducted with a standard non-Newtonian fluid, is 0.57%.
