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.
