Synchronous Driving Linear Move Irrigator can irrigate in variable rate by change driving speed. To improve the irrigation effect, studied water distribution information in both longitudinal and transverse directions while the linear move irrigator was drove synchronously ahead with different control method. With three-dimensional models and particle system, together with water distribution and water flow trace, three-dimensional dynamic model of water flow was built. Studied irrigation uniformity in longitudinal direction in different speed, analyzed the effect of sprinkler space and height to lateral irrigation uniformity, and optimized the configuration of sprinklers. Simulation results and field tests showed that: change the frequency of the drive motor can achieve vertical variable irrigation in driving direction, landscape direction irrigation uniformity depend on type and pressure of sprinkler. The maximum relative error between field and simulation of 3.39% shows that the simulation can reflex filed test. This study provides methods for linear move irrigator optimizing irrigation effect.
