Simulation Analysis And Design For Irrigating-sowing Machine

In this paper, According to the analyses of the Irrigating-SowingMachine, the mathematical models of parallelogram linkage, the double-diskdigger, seed drop tube, seed metering derives and the waterway sysrems wereconstructed. The study works of the thesis were as follows:1.The mathematical model of parallelogram linkage of irrigating-sowing machine was constructed. The computer simulated this model. Theresults of the computer simulation show the relationship of the plantingdepth stability and parameters of planter unit as well as soil resistemce.2.The motion equation of the double-disk digger and mathematicalpattern were established。The motion of the double-disk digger and theditch's shape were simulated and analyzed by the computer. Simulatingthc different ditch's shape with the different parameters.3.The Discrete Element Method analyzing model of the seed meteringdevice was established. Such contents were introduced as seedsgeneration , neighborhood search & contact detection. The motionequations of seed were estabtished, and then the mathematical model ofmain parameters were estabtished.4. A dynamic seed spacing distribution model was established.Computer simulation is made for the seed spacing distribution of the corn.The whole moving process of seeds on the seed drop tube was described.5. The waterway systems critical components parameters models wereset up. Computer simulation was made for the model. A quadric regressionmodel of spatter area of irrigating water about the three factors wasestablished. Cruves were painted through program.
