用电子显微镜研究了蝗虫足掌的微结构 ,用非线性有限元方法分析足掌接触过程的变形规律、接触刚度及接触面积、气囊的作用和足掌的应力应变规律 .结果表明 ,蝗虫足掌以软性外表皮包含血浆 (液体 )的结构形式 ,有利于降低接触刚度、增加接触面积 ,并使爪垫在接触过程便产生有利于稳定附着的摩擦力 .软性外表皮内的树丛状杆组织结构会提高足掌在各种表面上的适应性 ,降低足掌内部的应力 The microstructure of grasshopper foot was studied by electron microscopy, and the deformation law, contact stiffness and contact area, the role of airbag and the stress and strain of footpad were analyzed by nonlinear finite element method. The results showed that the grasshopper The structure of the soft epidermis, which contains plasma (liquid), helps to reduce the contact stiffness, increase the contact area, and make the claw pad produce a friction force for stable attachment during the contact process. Organizational structure will improve the surface of the palm of your hand in a variety of adaptability and reduce the stress inside the foot
