With increasing demand for passenger transportation and demand for high speed and high performance helicopters for defense vibration control has become an important design objective of modern helicopters so careful analysis is necessary to determine and eliminate source of vibration Vibration levels in helicopters are very high when compared to fixed wing aircraft There are many sources of vibration further lightweight aircraft structures have many natural frequencies and mode shapes%%%
