主 题：coupling bionic anti-erosion sand blasting test stress wave bionic layered structure
摘 要：The scales of body surface of Laudakia stoliczkana have the morphology of convex hulls,which are arranged in groove structure in macroscopic *** body surface skin is mainly composed of thesoftlayer of keratin and thehardlayer of the cuticle covering on thesoft*** coupling effect of the scale morphology and skin s structure gives Laudakia stoliczkana the excellent ability to resist the sand erosion in desert *** by the convex surface morphology and the composite structure of thesoftandhardlayers of the skin of Laudakia stoliczkana^the coupling bionic samples are febricated and the erosion resistance performance is *** test results show that the coupling bionic samples have good erosion resistance perfbimance and the samples with spherical convex hull exhibit the best erosion resistance ***,based on the theory of stress wave propagation in solid the numerical simula tions of particles impacting to the coupling bionic samples and bionic layered structure are done respectively and the anti-erosion me chanism of the bionic layered structure is *** simulation results are consistent with the experimental results,which show that the coupling bionic samples can effectively reduce the amplitude of the incident stress wave,and thus can prevent the failure of samples.
