Dynamic dynamometer LUD series

digitalimpactportable

Overview
The LUD shock dynamometer is an electromechanical test bench designed for controlled testing of shock absorbers, dampers and suspension components. It combines software‑controlled variable stroke and speed with portability and low power consumption, offering capabilities similar to higher-end electrodynamic systems while remaining compact and transportable.

Features

• Max. peak force: 20 kN (dependent on model/configuration)
• Road profile replication
• Variable stroke (software adjustable)
• Max. stroke: 350 mm
• Contactless temperature sensor
• Free mounting length: 1300 mm
• Safety enclosure included
• 100% electric, low power consumption

Type of test

• Performance testing
• Durability / fatigue testing

Applications

• Shock absorbers
• Dampers
• Suspension systems

Advantages

• Fully adjustable stroke and speed via software (programmable cycles: sinusoidal, triangular, etc.)
• Up to 350 mm stroke for extended travel testing
• Peak force up to 20 kN depending on configuration
• Road profile reproduction for realistic loading
• Effortless installation and transport
• Intuitive, user‑friendly interface
• Low operating power (100% electric)
