Abstract :
This paper deals with the compressibility of ultrasonic compaction. The object is to find out the most effective factor in increasing the density of the compaction for high efficiency electrical motor with soft magnetic composite under ultrasonic action. To make clear the effects of the ultrasonic vibration on the target process and obtain general knowledge usable for the practical design, several model experiments were proposed and carried out. The improvement in the resultant density was studied as function of the compression pressure, the vibration amplitude/frequency and the input power. Through the experiments, the fundamental information such as densification mechanism under ultrasonic action and the optimum design parameter for the high densification were figured out.
