Damping ratio for each wheel (dimensionless quantity). This is an alternative method to the EUSAMA, where ‘efficiency’ of dampers is evaluated directly. In engineering the Damping ratio is a generally used dimensionless measure describing how oscillations in a system (wheel on the car body) decay after disturbance.

Minimum phase shift is the extension / alternative method to the EUSAMA test method, suitable also for a very light car testing. In engineering similarly as the Damping ratio, Phase shift is also used as a measure of damping properties of oscillating systems.

EUSAMA evaluates minimum adhesion value between the wheel and the road.

Suspension test result eveluation according to any of the three implemented test methods (EUSAMA, Minimum phase shift and Damping ratio). None of these three test methods requires comparing to the database of the vehicle/damper specific reference values.

Based on more than 20 years experience from Belgian PTI stations, heavy duty versions of suspension testers are capable to perform 100 – 300 car tests/day over period of 10-20 years.

Suspension testers – from the basic one to the most advanced ModularTest was founded in 2011 with the intention to offer a series of suspension testers on top of roller brake testers. These suspension testers cover not only the limited requirements of small garages but also the requirements of large Periodical Technical Inspection (PTI) vehicle More…


30.3.2014 – Combo lane MCP400 on Autotechnika – Brussel

Our combo tester MCP400 was presented on Autotechnika 2014 in Brussel on the stand of our Belgian distributor, the TAE company.

25.11.2013 – New product – combo tester ST200

We are proud to announce the new product. The MCP400 is the combination of the EUSAMA suspension tester and the roller brake tester in a single compact (and price effective) frame. This combo tester is our answer to a market demand of an affordable test lane for any garage. The suspension tester part of MCP400 More…

22.7.2013 – The Damping ratio software

EUSAMA principle suspension testers (or resonant adhesion principle suspension testers) based on their specification mostly measure only minimum adhesion or road holding, the Eusama value. But this value is unfortunatelly especially on small cars rear axles strongly influenced by incorrect tire inflation or nonstandard axle load. On that account we implemented on EUSAMA suspension testers More…
