摩擦摆隔震支座固体润滑技术综述

随着隔震技术的发展，摩擦摆隔震支座因其隔震周期与上部结构质量无关且具备自复位能力等独特优势受到日益广泛的关注。保证摩擦面稳定的低动摩擦系数是推动其工程应用的关键。目前，美国摩擦摆产品多使用航空航天领域的固体润滑技术，而此类技术应用于摩擦摆的相关研究在我国尚处于起步阶段，亟需进行系统梳理和思考。文章简述滑动摩擦界面固体润滑的基本原理，梳理国内外摩擦摆和其他滑动型支座固体润滑技术的研发情况，对金属和金属氧化物、过渡金属二硫化物、工程塑料这三大类常用固体润滑材料的优势和不足进行分析，总结滑动型支座常用的摩擦系数测试方法，讨论速度、压强、温度和表面粗糙度等因素对试验结果的影响，对比摩擦摆隔震支座固体润滑的理想工作阈值和国家现行标准的技术要求，最后给出对固体润滑层技术未来研究方向与研究内容的相关建议。

Review of solid lubrication technologies for friction pendulum system

Friction pendulum system (FPS) or friction pendulum bearing (FPB), has attracted wide attention owing to its unique properties, including the isolation period unrelated to superstructure mass and the re-centering capability. In its practical applications, however, consistent and low friction solid lubricant layer of ensuring stable friction surface is still a crucial challenge for FPS. The commercialized FPS products in the US have adopted aerospace-based bearing materials for sliding interface, but these bearing materials have not been thoroughly studied in China. As the FPS research in China is still at the starting stage and systematic review on the topics of solid lubricants is absent, the contact and transfer mechanisms of solid lubricants at the sliding frictional interface are introduced. The solid lubricant materials are summarized into three major categories: metal and metallic oxides, transition metal disulphide and engineering plastics. Furthermore, the advantages and disadvantages of these materials are discussed. The testing methods on friction coefficient are summarized, and the influences of velocity, pressure, temperature, surface roughness and other parameters on test results are discussed. The ideal working limits of the solid lubricant layer are compared to those in the Chinese standards. Finally, the suggestions on future research directions and research contents of the solid lubrication technologies are proposed.
