摘　　要：采用有限元分析法,以TBD234V6型高速柴油机B列排气管为例,使用ANSYS建立柴油机排气管的模型,通过仿真分析排气支管长度、排气管出口的弯折度角度对排气情况的影响。研究表明,适度缩短排气支管长度和增加排气管出口的弯折度角度可以有效改善系统的排气效率,但其增加的长度也受到柴油机的整体尺寸的限制。The finite element analysis method is used,taking the B exhaust pipe of the TBD234V6 high-speed diesel engine as the research object,using ANSYS to build the diesel engine exhaust pipe model.The influence of exhaust pipe length and exhaust pipe outlet bending degree on exhaust condition is analyzed by simulation.It is found that the exhaust efficiency of the system can be effectively improved by shortening the length of exhaust branch pipe and increasing the bend Angle of exhaust pipe outlet.But it was limited by the overall size of the diesel engine.
