The LDS V9940 is the largest and most powerful shaker in the LDS by HBK range — over 65,000 lbf (300 kN) of peak sine force, nearly 180,000 lbf (800 kN) of half-sine shock force, and a 30 in (760 mm) armature engineered for extra-large test articles up to 11,000 lb (5,000 kg): complete EV battery packs, e-axles, e-powertrains, spacecraft structures, and full product-level assemblies. Water-cooled and optimized for shock performance through pedestal bearing assemblies that minimize moving mass, the V9940 delivers the industry's most proven large-shaker architecture as a fully integrated system — slip tables, head expanders, fixtures, and controls working together from day one.

Proven at NASA: NASA's Marshall Space Flight Center in Huntsville, Alabama recently installed an LDS V9940 water-cooled shaker system to simulate launch and space-flight environments for large spacecraft payloads — running the same platform on a large bearing-guided horizontal slip table to move and test massive flight hardware. When the test article is a spacecraft, the shaker is the one thing that can't be the question mark.

Applications

• EV battery pack certification to UN 38.3 and UNECE R100 (50 g/30 g, 6 ms and 11 ms pulses) and ISO 12405 (25 g, 15 ms)
• Spacecraft and launch-environment simulation, supporting test programs to NASA GEVS (GSFC-STD-7000)
• Half-sine shock testing to nearly 180,000 lbf (800 kN) peak force — the highest shock capability in the LDS range
• Vibration testing in all three orthogonal axes via HBT1500/HBT2000 slip table and head expander configurations — resonance search, sine, random, sine-on-random, and transient excitation to 2,000 Hz
• Large-footprint battery testing with pedestal bearing layouts that support the payload perimeter while keeping moving mass low
• Combined-environment testing when paired with an AGREE chamber — simultaneous vibration with temperature and humidity profiles
• End-of-line production screening and process validation at full assembly level

Key specifications

Over 65,000 lbf (300 kN) sine force, peak · nearly 180,000 lbf (800 kN) half-sine shock force, peak · 11,000 lb (5,000 kg) payload capacity · 30 in (760 mm) armature · 5–2,000 Hz usable frequency range · 100 g sine acceleration · 2.5 in (63.5 mm) shock displacement · payloads up to 10 ft (3 m) as standard

Why V9940 over competing large shakers: No competing electrodynamic system publishes shock force at this magnitude — nearly 180,000 lbf of half-sine shock puts full battery-pack shock certification on a single platform instead of a drop tower plus shaker. The pedestal bearing architecture is purpose-built for large-footprint payloads: bearings positioned around the slip table perimeter carry the load so a smaller, lighter slip plate delivers higher resonance and cleaner dynamics. It's the platform NASA selected for spacecraft-level testing at Marshall Space Flight Center, backed by an LDS installed base and parts availability measured in decades, not product cycles, and HBK's global calibration and support network.

This reliable and proven shaker platform is ideal for vibration and shock testing of Electric Vehicle (EV) battery modules and packs, e-axles and e-drivetrains.

The LDS V9940 is suitable for high-acceleration shock tests, as well as for testing with sinusoidal, random, and transient excitations. Providing high Half Sine Shock force, the water-cooled shaker is capable of testing the most demanding payloads.

The design includes optimised table designs using innovative pedestal assemblies to minimise moving masses, greatly improving performance.
