W1: Non-Contact Vibration Characterization, David Oliver, Polytec Inc.
8:00am - 5:00pm (includes a 1 hour break)
Workshop Overview: Laser Doppler vibrometry has been used for non-contact vibration characterization for several decades by leading research institutes and companies. The technology has become instrumental in a wide range of applications that include automotive, aerospace, defense, data storage, micro electronics (MEMS), ultrasonics and medical industries. Non-contact vibration sensors are being used for basic research, design development, model verification, process control, and to troubleshoot unwanted vibration. A wide variety of laser Doppler vibrometers are available, each tailored towards specific needs. Single point vibrometers measure the vibration response at just one location. Dual beam vibrometers are used to measure vibrations at two points to remove common mode vibrations. Rotational vibrometers measure the dynamics of a rotating shaft or spindles. Among the higher-end systems, 3D scanning systems are used to measure a tri-axial response and map the vibrations across the entire surface of an object.
The morning session of the workshop will be focused on dynamic characterization of macrostructures (structures ranging in dimension from 1cm to 10s of meters) and the afternoon session will be geared towards microstructure applications. Each workshop session will consist of two parts: 1) an overview over the fundamental principles of laser Doppler vibrometry and how it integrates seamlessly into the design and development process, and 2) a hands-on demonstration on Polytec's high-end scanning vibrometers.
Workshop Objective:This Workshop shall provide a broad theoretical overview of the technology of laser Doppler vibrometry for different applications. The real life demonstration as well as the hands-on session will equip the attendee with the understanding necessary to tackle his own measurement challenges. This workshop is addressed to anybody with a technical background having an interest in vibration testing.
