Experimental investigation on inertial actuators arrangement optimization for active control applications

Abstract

Active control of noise transmitted through structures has been gaining a significant interest. The authors have developed an idea of active casings reducing noise generated by devices. For such noise barriers which vibrations are actively controlled, locations where inertial actuators are attached are crucial. It determines the barrier performance to a great extent. However, its not obvious what is exactly the advantage of a precise modeling and optimization over a random or quasi-random arrangement. Depending on the barrier complexity, the modeling and optimization process may be difficult and time consuming. This paper presents a study investigating this aspect with experimental results, attempting to answer whether the effort are worth the obtained results.
