Abstract:
The vascular mechanical parameters are important indicators for human vascular and they play important roles in clinical research. This paper developed a new vascular mechanical properties testing system. This system not only realizes the tensile rupture test in one dimensional, but also the reciprocating tensile test for vascular, which provides more comprehensive experimental data and theoretical basis for the study of human vascular. The system consists of three parts: the mechanical platform, hardware circuit and upper computer system. The mechanical platform transforms the rotation movement of motor into linear movement via the structure of bal screw. And the bal screw and tension sensor are connected, which is used for mechanical data reading. The displacement data is col ected by displacement sensor. Experiments show that the accuracy is better than 0.292%, and could meet the demand of the testing of vascular biomechanical characteristics.
