游艇桅杆在动态载荷下的缺陷检测
Dynamic loading on a yacht mast
该示例展示了对30米碳纤维复合材料（CFK）游艇桅杆的无损检测应用，检测团队采用SE1传感器结合振动激励设备（Piezoshaker）进行动态载荷测试。时间平均检测结果揭示：桅杆表面裂纹下方存在更大范围的深层脱层缺陷，该缺陷起始于一个微小可见的裂纹。这一发现颠覆了“小裂纹无需修复”的传统认知——通过振动模态分析，可精准判断裂纹是否关联结构性缺陷，避免过度维修或漏检风险。
The example shows an application of NDT on a 30m CFK yacht mast (lower left). The time average result of the SE1 measurement and dynamic loading by our Piezoshaker (lower right) is indicating a larger delimitation below the surface starting from a small visible crack. Usually, small cracks are often seen on the surface, but not all are related to delamination, which needs any repair.
