Improvement of High Pressure Driveing Research Method and Study on Velocity of Article Motion

YAN Zhi xin 1,2 , WU De lun 1, WANG Hou yu 1, ZHENG Zhou lian 1 (1.Faculty of Civil Engineering, Chongqing University, Chongqing 400045,China; 2.Faculty of Civil Engineering of CSFU, Changsha 410000,Hunan,China)  
By analysing the testing principle of two dimensional particle motion and applying the technology of high speed narrow gap scanning photography, a new testing system has been established. This system can acquire the locus and velocity of two dimensional particle motion. Thus the new testing system has widen the studying field of high speed narrow gap scanning photography from one dimension to two dimension. The author has compared two kinds of testing systems and gotten the photographs of body movement by using new testing system. Article motion has been studied under high pressure. At the same time, projection velocity and projection angles have been acquired.
