  • Design of Step-type Ultrasonic Horn with Non-uniform Temperature Distribution

抄録

<p>A design method of a step-type ultrasonic horn with non-uniform temperature distribution was studied with the aim to apply ultrasonic technologies to high temperature engineering applications. First, an alloy casting system with ultrasonic transmission using the horn was modeled by a theoretical link between heat transfer and sound propagation. Next, the design optimization method of the horn with non-uniform temperature distribution was presented. Based on the method, the characteristic lengths of the step-type horn, x1 (axial length of small-diameter part), x2 (axial length of large-diameter part), were calculated by varying design conditions: properties of material, temperature difference, and frequency. Defined by an odd multiple of one-quarter cycle of ultrasonic wave, the value x1 increased stepwisely with the temperature rise of a specimen. On the other hand, the value x2 decreased slightly with the temperature rise. Both the lengths x1 and x2 were decreased with increasing frequency. It was demonstrated that a machinable ceramic horn can be made compact in the design compared to a duralumin horn.</p>
