1. LINEAR ULTRASONIC MOTOR WITH TUBULAR GEOMETRY / MOTOR ULTRA-SÔNICO LINEAR COM GEOMETRIA TUBULAR
This work presents the study on a linear ultrasonic motor with tubular geometry for linear displacements. Similar topologies, reported elsewhere, are conceived for producing rotary motions. Due to some particular characteristics of this geometry, not explored yet, a new study on interaction between resonance modes in a hollow cylinder for linear movement gen

2. Contribuição ao estudo tribologico dos pares acionadores de motores ultra-sonicos
A tribological study of the potential materials to be employed in linear ultrasonic motors is presented. Different pairs of materiais such as steel/alumina, steel/diamond, alumina/diamond and diamond/diamond have been studied. The diamond samples were obtained by chemical vapor deposition (CVD) and used in the ultrasonic pairs without any previous polishing.
