为实现对水润滑艉轴承及其传动系统的综合性能测试,开发了一种水润滑艉轴承综合性能实验平台,设计了实验平台测试方案,并对其重要部件进行了结构设计和动力学分析,结果表明其结构不会发生共振。该实验平台能模拟水润滑艉轴承及其传动系统的复杂工况,在线检测水润滑艉轴承工作转速、转矩、温度、摩擦特性、水膜压力分布、轴心轨迹、噪声、水膜的动刚度系数和阻尼系数等各项参数,为建立水润滑艉轴承系统实验与评价体系,掌握水润滑摩擦副的承载、失效机理与演化规律、摩擦学性能与动态服役行为等关键科学问题提供实验条件。
In order to realize the comprehensive performance testing of water lubricated 艉 bearing and its transmission system, an experimental platform of water lubricated 艉 bearing comprehensive performance was developed, the test program of the experimental platform was designed, and the structural design and dynamic analysis of its important components were carried out. The results show that the structure does not resonate. The experimental platform can simulate the complex conditions of the water lubrication 艉 bearing and its transmission system, on-line detection of water lubrication 艉 bearing work speed, torque, temperature, friction characteristics, water pressure distribution, axis trajectory, noise, water film motion Stiffness coefficient and damping coefficient and other parameters to provide experimental conditions for the establishment of water lubrication system research and evaluation system, to master the bearing, failure mechanism and evolution law, tribological properties and dynamic service behavior of water-lubricated friction pair .
