| Abstract: | The motion parameters of stratifying course in jigging were studied with jigging system and highspeed dynamic analysis meter under the different opterating conditions. Using high-speed dynamic analysis the motion of jigging bed was observed within an interval of 10-2-0. 5 X 10-3 s. So some phenomena were found that couldn't find with common means. From the experiment and analysis, the curves of position, velocity, acceleration, energy, and force were obtained with the special analysis software. It indicates that the dynamic causation of stratifying is pulging water and ascending flow plays an important role. |
