ON THE THEORETICAL DAMPING AND FORCE VIBRATION ANALYSIS OF THE EXHAUST SYSTEM
Keywords:
KeywordsAbstract
In.this paper a damping hanger is considered as a method to isolate
the vibration to the body of the car. In the procedure. the internal
noises have been taken into consideration. The flexible bellows
effects is .also studied using forced vibration analysis. This analysis
is performed below 50 Hz. Using a selected excitation frequency
response function at a recommended hanger location. the behaviour
ofthe exhaust system and vibrations can be determined.
