The FVA-Workbench goes far beyond the basic functionality of typical gearbox design software, offering a number of expansion options that increase its versatility in various application scenarios. Users can implement their own scripts to automate specific calculations and develop customized solutions. This makes the FVA-Workbench a key component in the lifecycle management of gearboxes. Furthermore, combining the FVA-Workbench with modern data acquisition methods enables deeper analysis of sensor data from physical systems. This makes it possible to detect anomalies in operation at an early stage and quickly identify the effects of system changes, which opens up new potential for predictive maintenance and machine optimization. Thus, the FVA-Workbench proves itself to be not only a powerful tool for the design and calculation of gearboxes, but also a foundation for innovative applications within the context of Industry 4.0. The integration of live data, for example via OPC UA, allows for more precise calculations, as measurement data for individual gearbox elements is fed directly into the FVA-Workbench, making it possible to perform calculations using actual data instead of just nominal values. These new models along with the evaluation of live data can be used to create digital twins which contain data from across the entire product lifecycle.
