Electrodynamic shaker KUD series

Product overview
KUD is the electrodynamic series for high-dynamic durability testing of shock absorbers and suspension systems. Designed as a replacement for hydraulic rigs, the KUD series delivers peak forces up to 160 kN and continuous dynamic loads up to 82 kN while supporting high speeds and long-duration cycles.

Short specs
Max. continuous dynamic force: 82 kN
Max. peak force: 160 kN

Type of test

• Duration (long-term fatigue/durability)
• Reliability and performance validation

Applications

• Shock absorbers and dampers
• Suspension components and sub-assemblies

Features (high level)

• Special linear guides engineered for multi-billion cycle life
• Electrodynamic linear motors with reduced inertia
• Optimised cooling system for continuous and extended tests
• Closed-loop force and displacement control via Test Center controller
• Support for optional hardware to cover a wide range of performance tests
• Generation of diverse waveforms: sine, triangular, square, sine-on-sine, sine sweep, double-speed sine/triangular, block cyclic
• 24-bit high-resolution data acquisition
• Separate, independent control station
• PC-based Test Center graphical interface for flexible test management
• Wide selection of grips, dedicated test accessories and load cells
• Integration capability with extensometers and climatic chambers

Advantages

• Dynamic performance suitable for high-frequency durability protocols
• Minimal maintenance due to absence of mechanical transmission
• Lower electrical consumption attributable to efficient electric motors
• Flexible geometric configuration and multi-sample support
• Plug & Play installation
• Competitive acquisition cost relative to hydraulic alternatives
