When testing the vibration behavior of lightweight or suspended structures, choosing the right excitation method can make all the difference. Traditional tools such as electrodynamic shakers and automated modal hammers have long been the standard, but each comes with practical limits —either influencing test results or slowing measurements due to sample movement and repeated impacts.
The Qsources Qlws inertial shaker provides a valuable alternative. It offers a smart combination of speed, accuracy, and ease of use. With its low dynamic mass and self-aligning design, it delivers reliable modal data without disturbing the structure— making it especially valuable for scanning vibrometer measurements.
In the article below, written by our distribution partner Polytec, the Qlws is compared to conventional excitation methods. It describes how the Qlws shaker speeds up testing time, and where it offers the greatest benefits for precise vibration analysis.
