长行程多油缸同步运行精度的测试研究

Study of test on the synchronous running accuracy for long stroke multi-cylinder

本文提出一种长行程多油缸的同步测试新方法，取代传统大量程传感器绝对位移测量方法，实现了实时检测，实践表明，方法直接、可靠。

A method of synchronous testing for long stroke multi-cylinder is proposed in this paper.The new method takes the place of the traditional absolute displacement measuring method which uses the long stroke measuring sensor,and realized real time detecting. It is proved in practice that the method is direct and reliable. It will have remarkable technical and economical value and broad application future.
