Abstract: According to the information of surface electroosmosis on the creatures, alternating current was used in electroosmosis on the soil bionic nonsmooth surface, and was experimented on. The effects of frequency of alternating current on the soil adhesion was studied. Using the experimental optimization technique, the effects of frequency and voltage of alternating current on the soil adhesion were tested, and a notable regression formula was obtained. The theory basis was founded for the application of alternating current in bionic nonsmooth surface electroosmosis.
