In this work, we proposed an effective way to fabricate a tangentially polarized composite cylindrical transducer with high electro-mechanical coupling coefficient (EMCC) by radially connecting an inner tangential polarized piezoelectric tube with an outer metal ring. The resonance frequency and EMCC of the proposed transducer are calculated according to frequency equations, which are obtained from...
The analytical thermal model of the grinding process is an important tool for predicting temperature to minimize workpiece thermal damage while improving process efficiency. As more and more numerical models are developed for the grinding temperature research, the established analytical model can be validated with numerical method. A new analytical thermal model of arc moving heat source for rectangular...
Abrasion is a stochastic process. It has been realized by some researchers that Monte Carlo simulation is a powerful tool to predict the wear rate of materials. The important issue for the simulation is to collect necessary basic data of worn materials, such as, ductility, plasticity, hardness, etc. The most difficult work, however, is to get parameters related to wear system. A factor, which divides...
