Abstract

Understanding stiffness degradation and developing suitable damage detection method for composite helical springs (CHSs) are important for their application and further development. In this study, a coupled plasticity-damage model for capturing stiffness degradation of CHSs with multi-braided layers (MBLs-CHS) is developed. Experimental results show that there is minor damage that only happens in the resin component of MBLs-CHS during impact. The element removal fraction in the simulation result is used to evaluate the damage severity, which is suggested to increase with impact energy (E_i) and decrease sequentially for CHSs with single, double, and triple braided layers (i.e., SCHS, DCHS, and TCHS). Specifically, damage severity of TCHS decreases by 51.3 % under 60 J impaction compared to that of SCHS. Finally, the time domain analysis method is introduced to monitor damage in real time. The amplitude intensity profiles under various Ei of CHSs have been fitted to predict the global stiffness degradation of CHSs in real time.

了解多编织层复合螺旋弹簧在冲击力作用下的刚度衰减情况

了解复合螺旋弹簧（CHS）的刚度退化并开发合适的损伤检测方法对其应用和进一步发展非常重要。本研究建立了一个塑性-损伤耦合模型，用于捕捉具有多编织层的复合螺旋弹簧（MBLs-CHS）的刚度退化。实验结果表明，在撞击过程中，只有 MBLs-CHS 的树脂成分会发生轻微损伤。模拟结果中的元素去除率被用来评估损坏严重程度，对于具有单层、双层和三层编织层的 CHS（即 SCHS、DCHS 和 TCHS），损坏严重程度随冲击能量（Ei）的增加而增加，并依次降低。具体而言，与 SCHS 相比，TCHS 在 60 J 冲击力下的损坏严重程度降低了 51.3%。最后，引入了时域分析方法来实时监测损坏情况。通过拟合 CHS 不同 Ei 下的振幅强度曲线，可以实时预测 CHS 的整体刚度退化。
