Abstract
Analysis of Noise, vibration and Harshness (NVH) of the car door was carried out, the door component is a very vital body in the passenger car, it not only provides safety against the outside obstacles which are disturbing driver and occupants and it also protects from wind and also offers aerodynamic effects while in motion, door will vibrate due to wind force and by the less strong weak reinforcement, this can be overcome by adding some Vibration Dampers. Initially numerical analysis is conducted for conventional car door for without and with viscoelastic damping material at free – free condition. In the next step, Experimental modal analysis is carried out for automotive car door for without and with viscoelastic damping at same condition. Natural frequencies and mode shapes were collected at both methods and compared together; Hence, it proved that component with viscoelastic damping material one was better than conventional one
