| Summary: | The purpose of this project is to study the effect of Dynamic Vibration
Absorber (DVA) to reduce the humming type noise and vibration of the Proton Exora.
The DVA was designed and tuned according to the natural frequency of the AC Pipe
structure and applied to the system and vehicle level of the Proton Exora HVAC sytem.
The humming type noise and vibration characteristics of the HVAC components were
recorded and compared before and after the implementation of DVA. The
implementation of DVA was found to improve the vibration level of the AC Pipe by
80% and subsequently improving the noise and vibration level of the whole HVAC
system by 1.5 dB. It has been observed that the DVA has an effective frequency range
of 100 – 500 Hz for the vehicle level and 75-250 Hz for the system level. |
