摘要
运用Pro/Engineer软件,作出滑动轴承径向油膜压力分布曲线图,并求出油膜曲面面积,从而得到了滑动轴承径向油膜压力平均值。传统手工作图将滑动轴承径向油膜压力分布曲线画在方格纸上,通过数格法得到近似曲面面积,误差大。通过Pro/Engineer软件作图简单、美观、精确,值得推广。
The pressure distribution curve of radial oil film in sliding bearing was plotted using software pro/Engineer, but also the curve area of oil film could be attained. Therefore, the mean pressure of radial oil film in sliding bearing was calculated. The drawing error brought about by ordinary way is large because the pressure distribution curve of radial oil film in sliding bearing was placed in a square paper and the curve area could be approximately got in terms of number - grid method. Pro/Engineer-drawing is worth extending because its simplicity, beauty and exactness.
