针对柔性卷绕式空间太阳电池阵在发射阶段振动环境中的结构安全性问题，提出了一种基于卷绕预紧力和聚酰亚胺泡棉的创新性减振防护方案。该方案在无需额外复杂结构的情况下，仅通过调整卷绕预紧力和引入聚酰亚胺泡棉减振层，有效提升了空间电池阵的抗振性。研究首先建立了柔性卷绕式太阳电池阵的精细化仿真分析模型，然后评估了不同振动频率、振幅及预紧力对电池阵结构安全性的影响规律。在此基础上，对样机开展了相应振动试验，验证了论文方案在实际应用中的减振效果，试验实测结果表明该减振防护措施能够显著降低CIC电池的应变响应，减振效率达60%以上，同时，仿真和试验测试结果的一致性，也证明了论文分析模型的准确、可靠。

To address the structural safety of flexible roll-out solar array in the vibration environment during the launch phase， an innovative vibration reduction and protection method based on winding preload and polyimide foam is proposed. This solution effectively improves the vibration resistance of the battery array without the need for additional complex structures， simply by adjusting the winding preload and introducing a polyimide foam vibration damping layer. This study first established a refined finite element simulation model of a flexible wound solar array， and then evaluated the effects of different vibration frequencies， amplitudes and preload forces on the structural safety of the array. Finally， vibration experiments on a small engineering prototype verified the vibration damping effect of the scheme in practical applications. The results show that the design can significantly reduce the strain response of the CIC cell， and the vibration damping efficiency reaches more than 60%. The high consistency of the simulation and experimental results indicates that the vibration damping scheme has strong engineering feasibility and practical application potential.
