摘　　要：连续预压机升降位移准确性对压制板坯具有重要影响。应用电流测量法校正升降位移传感器的零点,并通过测量主油缸实际位移和传感器返回的电流值对位移传感器进行线性标定。结果表明,传感器出现零点漂移,线性标定修正了返回值误差,达到了预压机主油缸提升位移的一致性要求。Lifting displacement accuracy is of importance to produce panel for continuous prepressing machine. Current measurement method was applied to correct null points of displacement sensors. Linear calibration was used for return value of displacement sensors by measuring actual displacement of the main cylinders and current of the sensors. The results showed that null points of displacement sensors drifted and return value of the sensors was corrected by linear calibration. Therefore, lifting consistency demands for the main cylinders of continuous prepressing machine were met.
