Dynamic analysis of helicopter-mounted electronic equipment

Nowadays, an experimental study on the reducing weight and volume of an avionics component installed in a helicopter is necessary since it is be required to get the capacity of longer flight time and range. An avionics component is required to reduce weight and volume at once withstand dynamic loads from a helicopter. In the past, isolators has been applied to avionics components for reducing vibration and shock without distinction. But, isolator applied to an avionics component installed in a helicopter amplify vibration magnitude, and damage to a chassis, circuit card assembly and isolator itself by resonance at low frequency sinusoidal vibration.
