大型桥梁用液体黏滞阻尼器的耐久性讨论

Durability discussion of liquid viscous damper used for large bridges

在大型桥梁上运行的液体黏滞阻尼器必须具有良好的耐久性和抗疲劳能力。耐久性指标是阻尼器性能的综合体现。根据对美国泰勒公司阻尼器设计和生产过程的了解，结合龙江大桥阻尼器以及对泰勒公司阻尼器的设计过程、技术关键、生产管理，拟对阻尼器的耐久性问题进行剖析。可供阻尼器生产厂家参考，用于提高产品耐久性和使用年限，也可供结构工程师在进行设计分析工作之余，能够逐步认识阻尼器的构造原理以及生产过程。

Viscous damper operated on big bridge must be durability and anti-fatigue. Durability index is the combined reflect of damper performance. Depend on the design and production process of Taylor device, integrate with Longjiang damper, the design process, the technical key point, the manage regulation of Taylor device were introduced, the durability of viscous damper was analyzed. It can be referred by the damper manufacturer to improve the production durability and operation period, and can also be referred by structural engineer on their spare time to understand the configuration and production of damper.
