Experimental Study of Supporting Force of the Bionic Water Strider Model


Article Preview

Abstract. The supporting force model of the bionic water strider model was established through mechanical analysis, the critical conditions of which the bionic water strider model’s legs pierce the water surface were analyzed. The bionic water strider model with 4 legs was manufactured, super hydrophobic copper wire was fabricated, which was as the bionic water strider model’s legs. The maximum supporting forces of the bionic water strider model was measured through the test, which was compared with the calculated value according to the supporting force model, the error rate is 9.3%.
