研制了一种结构紧凑、经济实用的位移传感器。新的传感器，这是一个编码器，使用反射光电纤维，是足够小，可以嵌入模具内，以监测位移的金属板上的模具肩。通过一系列的拉深实验，证明了该传感器能够提供精确的毛坯运动信息。还提出了一种简单的方法来评估产品的应变，基于新传感器的读数。计算结果与实验结果吻合较好。
A compact, economic displacement sensor has been developed. The new sensor, which is an encoder using a reflective photoelectric fibre, is small enough to be embedded inside the mould to monitor the displacement of sheet metal on the die shoulder. A series of deep-drawing experiments has been conducted to prove that the new sensor can offer precise information of the blank movement. A simple method has also been proposed to evaluate the strains of the product, based on the readout of the new sensor. The results are in good agreement with experiment.
