HIGH DYNAMIC TESTING SYSTEM

At STEP Lab, we have introduced HUD, the ultimate solution for damper and shock absorber testing. This damper test bench is specifically designed for certain tests with specific features and advantages.

Applications

Testing of shock absorbers for automotive, motorcycle and heavy transport industries
Suspension/Shock absorber high dynamic tests
Characterization tests
Durability tests

Features

Closed loop control of force and displacement by Test Center control system
Reproduction of sinusoidal, triangular and custom profiles
High resolution data acquisition (24 bit)
Variable installation positions
Controller in separate and free position
Flexible programming of test sequences by Test Center graphic interface
Large variety of grips, testing tools and load cells
Integration with extensometers and climatic chambers

Advantages

Exceptional dynamic performance
Maintenance tending to zero thanks to the absence of a mechanical transmission
Low power consumption thanks to the high efficiency of the electric motor and absence of mechanical transmission
Possibility to manage up to 10 actuators in syncronised mode so as to create a 4-poster system
Flexible geometrical configuration: machine can be purchased as a linear actuator without upper crossbeam columns
Wide range of use thanks to programmable speed from 0.01 mm/s up to 8.000 mm/s and high stroke over 200 mm
Easy installation thanks to the request of only one electric socket and compressed air
