Abstract: This paper puts forward a new intelligent overall optimal algorithm, i.e., improved genetic algorithm, to work out the problem of high-speed moldboard plow surface for the first time. The best genetic operator can be attained by processing 6400 calculations. A corresponding program is compiled in Turbo-C language, the results of the simulation experiment show that the resolving time is 1/360 of the compound method, the specific resistance is reduced by 10.68% and the drag force is reduced by 6.16%.
