摘　　要：为了研究精度损失的变化规律，设计了一套基于角位移传递变化的实验系统。伺服系统控制脉冲产生，通过信号处理和计数电路，得到脉冲数据，由计算机软件控制数据的采集和分析。研究表明，该系统在每隔一段时间的多组采样数据中，转角差△咖的变化在0．15°～0．27°，且有上升趋势。对△φ的研究，可以寻找精度损失的变化规律，为采取相应的补偿措施提供依据。该系统总体设计合理，可用于精度损失变化规律的研究。A system based on change of angle displacement is presented in order to study the rule of accuracy loss. Servo motor driver controls generation of pulse, and the signal processing circuitry and the counter system give possibility of obtaining a great deal of date which is sent to be collected and analyzed by software. The study shows that the difference of the angle displacement varies between 0.15° -0.27° , as shown by lots of date analyzed, and the difference is likely to rise. The research leads to the rule of accuracy loss and offers basis for taking compensation measures. The System is suitable for studying the rule of accuracy loss.
