摘　　要：为探索蜘蛛网的结构与其优异力学性能之间的关系,利用ABAQUS软件建立蛛网的有限元模型,分析蜘蛛网在承受集中载荷和风载作用下的变形和应力分布.模拟结果表明:蜘蛛网可以承受较大的集中载荷,在很大程度上降低因应力集中而导致的蜘蛛网局部破坏;蜘蛛网能够承受较大风速而不发生破坏,但较大的变形不利于蜘蛛的生存.In order to explore the relationship between the structure of spider web and its excellentmechanical properties, we used ABAQUS software to establish the finite element model of spider web. Thedeformation and stress distribution of spider web under static load and wind load were analyzed. The resultsshow that the real spider web can bear a larger concentrated load and greatly reduce the local damage causedby the stress concentration. The spider web can bear the wind speed without damage, but the largerdeformation is not conducive to the spider survive.
