Abstract

A wavy circuit is one of the structures used in flexible devices, which endure high stretch ratios during operation. In this study, we focus on the importance of the section tilting angle of the wavy circuit. Both simulation and experiment reveal that the plane wavy circuit is highly affected by the buckling of the circuit, and buckling is influenced by the gap between circuits. On the other hand, the buckling effect tends to decrease when the tilting angle of the circuit section increases. We conclude that increasing the tilting angle of the wavy circuit provides an advantage in designing a flexible device that nullifies the gap-buckling tendency of the wavy circuit, and gives extra margin in the design process.

摘要

波浪形电路是柔性设备中使用的结构之一，它在操作过程中承受高拉伸比。在这项研究中，我们关注波浪形电路截面倾斜角的重要性。仿真和实验都表明，平面波状电路受电路屈曲的影响较大，而屈曲受电路间隙的影响。另一方面，当电路部分的倾斜角增加时，屈曲效应趋于减小。我们得出结论，增加波浪形电路的倾斜角为设计柔性器件提供了优势，它消除了波浪形电路的间隙屈曲趋势，并在设计过程中提供了额外的余量。
