Andreani DB4 suspension dynamometer
Taking the concept of suspension diagnostics to another level, Italian suspension specialist Andreani’s DB4 is a new generation professional dynamometer, optimized for suspension testing of motorcycles, cars and mountain bikes.
Thanks to the powerful 4kW AC-Motor, it allows you to test shock absorbers and forks in a wide range of speed and loads, choosing between several stroke settings.
Its advanced features allow any suspension operator to visualize a real time shock and fork load vs velocity graph, compare different click settings and valving options, measure dynamic suspension parameters and detect any operating anomalies.
The DB4 includes a state-of-the-art, real-time dedicated controller board that ensures a stable and reliable automation and deterministic data acquisition. The software provides an intuitive graphical user interface for data acquisition and simple but powerful tools for suspension analysis. It is compatible with the most common operating systems, and, as it is plug-and-play, does not require a dedicated laptop.
The graphs and numerical outputs of the software and its sophisticated algorithms allows you to fully define and characterize the suspension’s state of tune using peak velocity, load displacement and instantaneous velocity graphs. In addition to the viscous response of the suspension, the suspension dyno also provides gas preload, mean gas-spring rate and static friction outputs.
Custom versions of the software can include hysteresis analysis, dissipated energy and damping coefficient calculations.
