摘要
介绍一种由AST486计算机，光电二极管阵列编码器，磁电系动图式结构组成的生物材料扭转实验台系统，根据实验条件要求，由计算机输出信号控制磁电系动图式结构产生预定的扭矩信号驱动被测试样偏转。角位移采用光电二极管阵列编码器，实现非接触式测量。该系统设计新颖，动态特性好，能完成血管及其他生物材料的扭转实验，并由AST486微机对实验数据自动处理和分析。
This,paper introduces a biomaterial torque experiment apparatus which consists of AST486 computer,photodiode array,code device interface circuit,and magnetoelectric motional coil structure. According to experimental conditions,the computer sends out singnal to the coil which under the magnetic field is activated to producea series of desired torque and bring the sample to denect. Angular displacement is measured by photodiode arrayand code device system. The whole system has good dynamics and high precision and could finish a series of torqueexperiment for biomaterials,and AST486 computer can automaticlally conduct signals analyzing and data processing.
