This article presents a design method of Longitudinal-Bending Coupled Horn (L-BCH) giant magnetostrictive transducer utilized in spinning ultrasonic machining. The structural parameters are initially determined by the theory horn and thick disc. Then, effect rotating wheel on vibration characteristics L-BCH explored model harmonic response analysis through finite element method. Through continu...

Traveling Wave Ultrasonic Motor (TWUM) is a compact, precise, and silent actuator generating high torque at low speed without gears. Moreover, the TWUM has a high holding torque without supply, which makes this motor as an attractive solution for holding position of robotic arms. However, their nonlinear dynamics, and the presence of load-dependent dead zones often limit their use. Those issues...

Ceramics and other hard-and-brittle materials are very effectively processed by longitudinal-torsional coupled rotary ultrasonic machining (LTC-RUM), which cutting force evolution the effects of processing parameters on material removal mechanism need to be optimized. This study introduced LTC-RUM model zirconia ceramics based brittle mechanism. Firstly, kinematic analysis a single abrasive gra...

An approach to modeling the material removal rate (MRR) during rotary ultrasonic machining (RUM) of ceramics is proposed and applied to predicting the MRR for the case of magnesia stabilized zirconia. The model, a first attempt at predicting the MRR in RUM, is based on the assumption that brittle fracture is the primary mechanism of material removal. To justify this assumption, a model paramete...

Our climate system is undergoing severe changes because of a global economy based on fossil fuels and rising greenhouse gas emissions. Furthermore, the use non-renewable energy will be restricted in near future. As result, renewable has begun to assist our environment with clean energy. Solar frequently employed since it cost-effective source power. The objective this project design implement a...
