AI Technical Summary

Problems solved by technology

The bionic non-smooth elastic surface can reduce the frictional resistance between the elastic body and the solid, and the drag reduction effect is obvious. It is a brand-new drag reduction technology, but the current research on this technology is mainly concentrated in the theoretical analysis and numerical simulation stage. There is not yet a complete set of test equipment for bionic non-smooth elastic surface resistance testing, so the model test cannot be completed

Traditional drag reduction test research is usually carried out in testing machines such as friction and wear testing machines. However, due to its high cost, high cost, difficulty in daily maintenance, serious noise pollution, and various aspects of test conditions have certain limitations. And it is impossible to study the drag reduction test of bionic non-smooth elastic surface
