| 摘 要： | 为了研究水润滑橡胶合金轴承结构参数对其低速重载工况下摩擦噪声的影响,使用复模态分析方法建立了水润滑橡胶合金轴承系统仿真模型,采用专业仿真软件分析了不同摩擦系数及结构参数条件下摩擦噪声产生的概率,进而研究结构参数对摩擦噪声的影响,进行了平板型和圆弧型结构的水润滑橡胶合金轴承摩擦噪声的对比实验。研究结果表明,水润滑橡胶合金轴承的水槽半径大小、摩擦面形状以及摩擦副的摩擦系数对水润滑橡胶合金轴承的摩擦噪声有较大影响,而水槽的形状对轴承摩擦噪声的影响不大。对一定结构尺寸的水润滑橡胶合金轴承,水槽半径为4mm、平面型摩擦面的结构可以大大减少轴承出现摩擦噪声的可能性,相关实验结果与计算结果是吻合的。

| Abstract: | Complex mode analysis method is used to establish a water-lubrication rubber bearing alloy system simulation model in order to research the influence of structural parameters of water-lubrication rubber alloy bearing on friction noise under low speed and heavy load condition.The probability of producing friction noise under the conditions of different friction coefficients and structure parameters is analyzed by using professional simulation software, and then the effect of structure parameters on friction noise is studied.The friction noise contrast experiment of the flat and circular arc structure of the water-lubrication rubber alloy bearing is carried out.Analysis and computation results show that the groove radius, friction surface shape and the friction coefficient of friction pair are key influential factors on the frictional noise of water-lubricated rubber alloy bearing, while the effect of flume shape is very small.For the water-lubricated rubber alloy bearing with a certain structure and size, 4 mm groove radius with flat pattern friction area is optimal to reduce the possibility of bearing friction noise appearance.This computation result is verified by corresponding experiment. |
