【Abstract】 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.更多还原
