LDS (Ling Dynamic Systems) by Hottinger Brüel & Kjær (HBK) is the U.S. and global leader in vibration-test technology, delivering low-, medium- and high-force electrodynamic shakers, amplifiers and complete turnkey test systems. With thousands of systems deployed across North America and backed by the largest sales and field-service network in the USA and Canada, LDS supports major aerospace, defence and commercial customers such as Boeing, SpaceX, NASA and Amazon, delivering design, manufacturing and lifetime support to ensure product durability, mission-readiness and structural reliability under extreme real-world vibration, shock and seismic environments.
Core competencies:
Electrodynamic Shaker Systems: Full-spectrum shakers (air and water-cooled) for testing components to complete large systems, including EV batteries and satellites, with sine force ratings up to 300 kN.
High-Performance Power Amplifiers: Supplies stable, reliable power ranging from 75 VA up to 280 kVA to guarantee consistent testing performance across all scales.
Vibration Controllers and Software: Delivers advanced control systems (e.g., COMET series) supporting complex testing profiles like random, swept sine, and shock, ensuring test flexibility and stability.
