      目的 针对瓦楞缓冲结构设计未形成完整体系的问题，研究三角瓦楞缓冲衬垫的设计及缓冲性能。方法 首先，对三角瓦楞结构件缓冲机理及理论进行分析，得到三角瓦楞结构的缓冲临界承载特性；然后，以三角形支撑结构件为基础，依据三角瓦楞结构缓冲和临界承载特性建立三角瓦楞缓冲衬垫总体方案；最后，将三角瓦楞缓冲衬垫结构设计方法和步骤应用到瓦楞缓冲结构件实际设计案例中，并通过静态压缩测试试验来验证三角瓦楞缓冲衬垫的缓冲性能。结果 三角瓦楞缓冲衬垫设计实例表明，三角瓦楞缓冲衬垫设计方案可用于实际瓦楞缓冲结构设计开发中，为瓦楞缓冲结构件设计提供了计算依据。结论 得到了应力-应变曲线及三角瓦楞衬垫厚度和承载面积设计方法，可指导实际应用中三角瓦楞衬垫结构的缓冲设计，提升缓冲结构设计的效率。

英文摘要:

      The work aims to research the design and cushioning performance of triangular corrugated cushioning insert aiming at the problem that the design of corrugated cushioning structure fails to form a complete system. First, through an analysis on the cushioning mechanism and theory of triangular corrugated structural members, the cushioning and critical load characteristics of triangular corrugated cushioning insert were obtained. Then, on the basis of triangular support structure, the overall plan of triangular corrugated cushioning insert was established according to the cushioning and critical load characteristics of triangular corrugated structure. Finally, the structural design method and procedure of triangular corrugated cushioning insert were applied to the actual design case of corrugated cushioning structure, and the cushioning performance of triangular corrugated cushioning insert was verified through the static compression test. The design example of triangular corrugated cushioning insert showed that the design scheme of triangular corrugated cushioning insert could be used in the actual design and development of corrugated cushioning structure, providing a basis for the calculation of corrugated cushioning structural members. The stress-strain curve and the design method of triangular corrugated insert thickness and bearing area obtained herein can guide the cushioning design of triangular corrugated insert structure in practical application and improve the design efficiency of cushioning structure.
