Mathematical Model of Submerged Reverse Rotary Tiller and Parameters Optimization

The mathematical model of reverse rotary tiller was derived on the basis of relationship between design parameters (including geometric parameters and motive parameters) and power consumption. The objective function with the aim at the least power consumption was set up and Genetic Algorithms (GA) was applied to optimize the objective function. The best arrangement of the parameters was obtained with this method, and the optimal result was proved reseanable by the experiment.
