New generation of compact Vertical Pitch & Roll (VPR) shaker systems
Our latest generation of Vertical Pitch & Roll (VPR) shakers enables the multi-axial simulation of complex motion and excitation profiles, such as those experienced in vehicles, aeroplanes, helicopters and unmanned aerial vehicles. Highly dynamic, simultaneous excitation in the vertical direction, as well as synchronised inclinations around the transverse and longitudinal axes, realistically simulate multidimensional excitation forces and loads caused by uneven road surfaces, flight manoeuvres, and engine and drive vibrations. Simultaneously mapping several load scenarios enables coupling effects to be detected and analysed, providing more realistic data on material fatigue, structural strength and the long-term behaviour of test specimens, while significantly reducing test times. With excitation forces of up to 4 kN and a wide frequency range of DC–500 Hz, the systems can be used flexibly for testing sensors, cameras, navigation systems and radars. Integrated automatic load compensation supports larger components weighing up to 300 kg. Thanks to the low operating noise typical of the ALPHA shakers used, the system is also ideal for Buzz, Squeak & Rattle analyses on a wide range of vehicle components
