| 摘 要： | 使用SolidWorks软件对某中型汽车的排气系统进行三维建模,再对排气系统使用ANSYS Workbench软件进行模态分析,验证在外形结构和总体尺寸相同的情况下,三种不同管道截面直径下的排气系统的优劣性,得出在额定功率下排气管道截面直径为80 mm的排气系统更具有优势,在最大扭矩下,截面直径在90~100 mm渐变的排气管更具优势。

| Abstract: | The exhaust system of a medium-sized vehicle is modeled by SolidWorks.The modal analysis is performed on the exhaust system using ANSYS Workbench software to verify the advantages and disadvantages of the exhaust system with three different pipe section diameters under the same shape and overall size.The exhaust system with a cross-sectional diameter of 80 mm at the rated power is more advantageous.Under the maximum torque,the exhaust pipe with a gradual diameter of 90~100 mm is better. |
