Road load data acquisition: mobile data acquisition in the field
Vehicles and their components undergo numerous test runs from the first idea through to readiness for the start of production. From first "virtual load tests" only on the computer through tests in test stands and the "supreme discipline" of testing: mobile tests in the field (road load data acquisition).
The vehicles and components under test are subjected to real conditions of use, sometimes with extreme ambient and temperature conditions.
Mobile tests present specific challenges, in particular for measurement data acquisition: It is not enough just to provide the amplifiers with a rugged enclosure. It is essential also to take into account undesired influences on the measurement result such as extreme temperature variations. And, in addition: The test engineer should be able to access the measurement data in the field any time.
These ideas for next-generation mobile test and measuring equipment have been incorporated in HBM's SomatXR system which is outstanding for its ruggedness, high precision and maximum ease of use thanks to data transfer via the Internet.
