摘　　要：橡胶油封在装配过程中,塑性胶体容易产生不规则变形,由于变形曲线无法准确描述,从而影响了进一步的受力分析。结合数值分析中的牛顿插值法和曲线拟合法,提出一种分析橡胶油封变形曲线的新方法,并建立数学模型;利用Matlab软件对所建立的数学模型进行数值模拟,得到了橡胶油封理想的变形曲线。The plastic colloid is easy to produce irregular distortion by the force emerged during the assembly process of the rubber oil seal. The distortion curve is very difficult to describe accurately, which affects further stress analysis for the rubber oil seal. A new method to analyze the distortion curve of the rubber oil seal by adopting the Newton interpolation method and curve-fitting method was put forward, and the mathematic model was established. The established mathematic model was simulated by Matlab,the ideal distortion curve of the rubber oil seal was obtained.
