Active Force Control in Machinery Noise,
Abstract
The results in this investigation show that active force control is possible, and that large reductions in noise energy radiated can be achieved, although the system investigated here would not be ideal in a practical situation. The performance of the system is very critical on the timing of the control and excitation forces. For effective cancellation the shape of the force pulse or its spectrum must be matched exactly and the two opposite forces must act as closely together as possible on the structure. In this investigation the set up was more of a laboratory system and before any new improvements to the system can be made, better methods of implementation have to be found.
