【Abstract】 The moment actuators,as a new transducers,are used to measure the performance of the structure borne sound on the rotational degrees of freedom.In this paper,the distortionless moment power output and the corresponding electric power input of the moment actuators are measured,the coefficient of the power transformation is accounted too.更多还原
