As vibration testing evolves, a demand arises for tools that are smaller, smarter, and capable of delivering high-quality data without influencing the structure being measured. Traditional shaker systems often require external support, stinger alignment, or add undesired mass to lightweight structures.
Commercial accelerometers, general measurement front-ends, and Polytec's laser scanning systems are now able to detect smaller signals in a reliable way. The combination of these innovations and a significantly higher force to size/weight ratio allow for the use of self-supporting compact shakers for precise structural excitation —even in tight or hard-to-reach locations.
The Qsources Qlws shaker has been advancing the state of the art. The shaker is designed with patented internal suspension allowing for self-alignment. On top, its integrated force sensing and an ultra-light active mass enable accurate vibration measurements with minimal influence on the test object. Ranging from delicate carbon fiber components to full vehicle structures, the Qlws shaker offers reliable excitation across a wide frequency range, eliminating sample sway and alignment challenges which traditionally accompany impact methods.
In the whitepaper below you can explore how this technology improves modal analysis, transfer path studies, simulation correlation, and more —while reducing setup time and technician effort.
