摘　　要：为研究三维扇形斜面平台推力瓦的润滑性能,采用数值分析方法,通过Matlab软件计算水膜厚度、压力分布,使用有限元ANSYS软件获得推力瓦位移场和温度场的分布规律.研究表明:推力瓦块的压力呈两边低、中间高的趋势;水膜厚度与瓦块的几何形状有关;瓦块的最高温度和最大压力值均出现在推力瓦周向靠近出水口的位置.Numerical analysis method was used to study the lubricating properties of three-dimensional sector-shaped slope thrust pad. And the thickness and pressure of water film, deformation field and temperature field of thrust pad were all computed by ANSYS finite element method. Results show that the distribution trend of pressure of the trust pad is low on both sides, but high in the middle. The water film thickness has relation to the geometry of the pad, and positions of the maximum temperature and pressure values in the thrust-pad are all close to the outlet.
