Abstract: The delayed resonator (DR) is known for its ideal vibration suppression and simple control logic, but its operable frequency range is also known limited due to stability issues and practical hardware constraints. To extend ...

Abstract: Rotary ultrasonic machining (RUM) is an effective solution to cut, grind, or drill the advanced brittle hard materials. Contactless rotary transformer, with the advantages of high-power transmission efficiency and reliability, ...
