| 中文摘要: |
| 排气系统是汽车振动的重要来源。排气系统设计的好坏会关系到汽车的NVH性能。其中，橡胶悬置是将排气系统连接到车身最重要的部分，将直接影响排气系统传递到车身的振动以及能量的多少。从振动传递的角度阐述排气系统吊点位置的重要性，利用平均驱动自由度位移方法来确定排气系统的悬挂位置。通过平均驱动自由度位移方法确定排气系统吊点位置的仿真结果，能够在汽车开发前期给出指导性的建议，并在后续车型改进方面给予方向性修改指导。 |
| 英文摘要: |
| Exhaust system has a great contribution to the vibration of vehicle. The main construction is rubber mounts which connect exhaust system and the vehicle body. So the arrangement situation of rubber mounts has a direct relationship to the level of the energy and vibration which are passed to the vehicle body from exhaust system. This problem was researched and resolved by using the method of average driving degrees of freedom displacement. The simulation results may give some suggestions during prophase of vehicle development. |
