| Abstract: |
| This paper makes a microanalysis of soil slice force according to differential geometry on the basic of classical turning theory,sets up plough surface optimal math model by imitating soil paths,looks its energy requirement as goal function and looks agricultural requirement as restraining condition.Imitating experiment shows that the resolves of time in GA is 1/360 in compound mothed,the resistance of optimal plough surface is down by 10.68% and the draught is down by 6.16%. |
| Key words: high-speed plough surface,energy requirement model,optimal method,genetic algorithms (GA) |
