The mitigation of vibrations essay

Save Dynamic Propeller Balancing The most common source of aircraft vibration is the result of imbalance between the propeller and drive train. The vibration created due to the imbalance can effect a wide range of aircraft systems, such as: The dynamic propeller balancing procedure can be done on any aircraft in a flight-ready state.

A small vibration sensor accelerometer is attached to the engine in a location where vibration due to mass imbalance is at the maximum—at the crankcase spine as close as possible to the propeller flange.

A small tachometer pickup photo-tach is also mounted to the cowl or engine to produce a propeller tach signal.

The engine is operated and the vibration and tach signals are processed by the balancing computer. The balancing computer measures the vibration level magnitude produced by the accelerometer which corresponds to the amount of mass imbalance which exists.

About Andy Smith Electronic sensors capture and store recorded vibrations above a preset trigger level. Recorded data are then plotted against a curve representing the U.

The vibration and phase angle are used to compute a balance solution weight amount and location. The entire process usually takes runs and an average of hours.

Would you put tires on your car or truck without having a dynamic balance spin balance performed? Well, the propeller on your aircraft weighs as much or more than a car tire and can produce much higher vibration levels and is directly mounted to your engine.Mitigation of human-induced vibrations with DVF, DAF & CAF control laws on some idealised SDOF floor slabs with variable dynamic properties.
