Compact Multi-Axis Vibration Systems
Displacement up to 50 mm, Force up to 4 kN
Vertical Pitch & Roll (VPR) shaker systems from MB Dynamics provide compact, high-performance solutions for realistic multi-axis vibration testing. By combining vertical excitation with controlled pitch and roll, and mechanically coupled x and y responses, the systems enable up to five axes of motion. This allows accurate reproduction of real-world loads such as road unevenness, flight manoeuvres, drivetrain vibration and shock events.
With displacements up to 50 mm peak-to-peak, rotation angles up to 5.7°, excitation forces up to 4 kN and payloads up to 300 kg, the VPR delivers highly dynamic yet precise testing capability. A footprint starting at just 0.49 m² makes it ideal for space-restricted laboratories, while low operating noise supports acoustic applications including Buzz, Squeak & Rattle testing. Scalable and upgradeable, the VPR range adapts to future requirements.
