SHOCK DYNAMOMETER FOR ADVANCED DAMPER TESTING

shock dynos

LUD features

Shock dynos are essential tools for assessing the efficacy and resilience of shock absorbers and dampers. They replicate real-world scenarios, offering valuable insights into the performance of a vehicle’s suspension system across diverse conditions.

At STEP Lab, we have introduced the LUD Shock Dyno, the ultimate solution for damper and shock absorber testing. This shock dynamometer offers exceptional features and presents many advantages.

This shock dynamometer offers greater accuracy and functionality than basic crank and scotch-yoke dynamometers. Positioned in the market between our high-end models (HUD/XUD) and third-party entry-level options, the LUD provides a balanced solution with advanced features and improved performance.

  • Variable stroke and speed testing (fully adjustable by software)
  • Max. Stroke: 350 mm
  • Peak force: 20 kN
  • Replication of road profiles
  • Effortless installation process
  • Intuitive and user-friendly interface
  • Low power consumption (100% electric)
  • Easy to transport

SCOTCH-YOKE VS LUD

A New Standard in Damper Testing

The ‘LUD’ shock dyno offers a smarter, more versatile alternative to Scotch-Yoke machines, enabling advanced testing, real road profile simulation, and superior control through software.
