Using Exciters in Online Presentation

The Online presentation provides a detailed overview of the background, everyday practice, vibration measurement, and control intricacies of exciters (vibration exciters, shakers). We also address the identification of shaker faults, as well as regular and occasional maintenance. Furthermore, we discuss the necessary accessories, specifically focusing on the sizing and design aspects of specimen holders.

During the demonstration, we specifically deal with vibration measurement laying the foundation for control and the issues related to specimen holders.

Agenda of the Online Presentation

• Types and Basic Structure of Vibration Exciters (Shakers)
• Driving and Control of Shakers (based on vibration measurement) - role, structure, and operation of control - role, method, correct placement of vibration sensing
• Overview of Possible Faults of Vibration Exciters (Shakers) - faults in bearings/guidance (wear, breakage) - faults in water cooling or fan cooling systems - indications/faults of protective devices - faults in control/measurement loops
• Maintenance of Shakers (regular and occasional)
• Sizing and Design of Specimen Holders - role and impact of specimen holders in the shaking process - correct sizing and design of specimen holders - verification of properties of specimen holders
