For example, in-situ vibration measurements for testing spider webs in the jungle with portable laser vibration sensors revealed that the spiral silk threads in the web show high vibration damping properties, which immediately distribute induced energy into the radial silk threads. These preserve the structural integrity through dissipation of the supplied energy and thereby elegantly prevent a destruction of the web.Dynamic loads not only occur in spider webs but also in transportation: Extremely valuable patinings from museums are repeatedly transferred to other exhibitions, exposing them to hundreds of hours of travel stress. Such thousands of kilometers of road and air transport mean continuous low-frequency vibrations. But how to protect the valuable objects against these vibrations? Experts from the Geogia O'Keefe Museum succeeded in neutralizing the vibration influences by an vibration-optimized protective housing using innovative multipoint vibration measurement technology from Polytec. In addition to these exotic tasks, laser vibrometers solve countless measurement tasks every day in the field of technical product development and quality control: simply, quickly and accurately.
