Overall Process for Load Analysis

Ideally, the load analysis begins with the planning of a measurement campaign in which the operating conditions occurring during subsequent customer operation are measured on a prototype. The selection of the operating conditions to be measured need not be representative for the later use, but only has to cover all relevant conditions (for example a truck driving fully loaded on a country road in a mountainous area).

This can be supported by geo-referenced methods using VMC®. In the case of road vehicles, the result of this phase is a concrete route. The recorded data is then inspected, corrected if necessary and largely automatically segmented and classified with VMC® GeoLDA, i.e. broken down into operating states.

In order to be able to combine these operating states with the frequencies to be expected in the later use, the customer behaviour can be studied in parallel to the measurement campaign, or even in advance. This can be done, for example, by investigating field data, which is being collected more and more frequently and sometimes even in the full series, or by geo-referenced studies with VMC Usage Modeler.


Software for the Analysis of the Collected Data

The resulting usage model is then combined with the processed data to calculate consumption or load distributions and reference loads using U·Sim. Finally, the reference loads can be mapped on test tracks or standard load cases using multi-target optimization methods in U·SimOpt. Finally, the load distributions can be brought together with the component strength by Jurojin to calculate failure probabilities.
