Peter Sikora

Peter J. Sikora has 29 years of professional experience as a mechanical engineer. He worked as a test engineer, performing safety tests, e-mobility, and environmental requirements at RW TÜV Group for many years, gaining experience with different shaker types and controllers. Around this time, Peter began operating with Vibration Research software. His continuous self-learning and curiosity made him an enthusiastic user of the software, and he started to train others. At Vibration Research Europe, Peter is the Head of Training, where he applies his passion for the subject to explain the relationships between mechanics, software, and test requirements.

Presentation

Shaker extension control strategies for large test objects

Test objects often exceed the size of conventional shaker clamping tables. The parts of the test object that protrude from the table must be "intercepted" with an elaborate fixture and corresponding control strategy to eliminate undesirable effects. These fixtures are typically heavy and larger than the protruding test parts and generate unwanted interference. New developments by shaker manufacturers, combined with a sophisticated control strategy, show a trend toward constructing vibration tables with external supports known as extensions. Theoretically, external bearing-guided extensions allow clamping over a large area. What control strategy makes sense, and what does it look like in practice?
