Rotor/Bearing System Short Courses/Seminars
The Rotor Bearing Solutions International team has much experience in conducting industrial seminars in rotor bearing topical areas. The seminars are tailored to specific company needs and taught on a company site. With our very large existing volume of notes, from introductory materials to advanced rotor dynamics, rotordynamics analysis, fluid film bearings, active magnetic bearings, control of active magnetic bearing supported rotors and other materials – we assemble suitable materials for teaching industral seminars. Our industrial seminars can address a wide range of topics which are geared to and presented to address RBSI client needs, such topics may include:
