车辆排气系统的振动和噪声是影响整车性能的主要因素之一。在汽车发动机的激励下,排气系统的振动会传递到车身,进而影响车辆的舒适性。相关人员利用CATIA和ANSYS WORKBENCH软件,对某轿车排气系统进行三维建模和结构的模态分析,可以为后续排气系统的结构优化提供分析基础。
Vehicle exhaust system vibration and noise is one of the main factors that affect vehicle performance. Excited by the car engine, the exhaust system vibration will pass to the body, thus affecting the vehicle’s comfort. Relevant personnel use CATIA and ANSYS WORKBENCH software to perform the three-dimensional modeling and structural modal analysis of a car’s exhaust system, which can provide the basis for the structural optimization of the following exhaust system.
