| 摘要:利用ANSYS模拟计算了铸铁扬克烘缸在受外加线载荷、蒸汽内压以及自重情况下的变形以及应力分布情况，得到了线载荷区的变形曲线，并与实际工作过程中的变形进行比较。据此对扬克烘缸表面轮廓进行优化，计算出优化后扬克烘缸的变形和应力，与优化前的结果进行比较和分析，提出了扬克烘缸轮廓优化的具体实施步骤。 |
| Abstract:The deformation and stress distribution of cast iron Yankee dryer caused by outside linear load， inside steam pressure and self-gravity were calculated by numerical simulation with ANSYS software. The deformation curve of the linear load area was obtained and compared with the deformation in the actual working process. The surface profile of dryer was optimized and the deformation and stress of the optimized dryer were calculated and compared with the that of before optimization. In this paper， the method of the surface profile optimization of Yankee dryer was presented． |
