With the release of version 9, the FVA-Workbench once again sets new standards in gearbox design, enabling the seamless integration of the latest research results into industrial practice. As a groundbreaking interface between collective research and application, the FVA-Workbench accelerates development and innovation in drive technology. This new release is more powerful than ever, with innovative features for flexible load spectra and improvements in FEM components and shaft-hub connections.

New Features in FVA-Workbench 9

Flexibility in load spectrum calculations: individual power paths for each load stage

One new feature of FVA-Workbench 9 is flexible load spectrum calculations. In contrast to the previous method, in which the power was scaled across different load stages, this function makes it possible to define different operating states. Individual power paths and additional loads can be assigned to each operating state, particularly for consideration of auxiliary units. The time share, operating temperature, switching position, power flow data, and external loads can be freely selected for each load case. This data can easily be copied and pasted from Excel. A model snapshot can also be created for each load case, with detailed results that can be displayed in overview tables in the report. 

Efficient integration of gearbox housings: error prevention and faster workflows

The latest version of the FVA-Workbench includes new FEM features, especially with regard to split FEM gearbox housings. Gearbox housings can now be imported as an assembly of individual CAD components and linked together. This not only helps to avoid errors when merging CAD components, but also saves time thanks to coarser meshing of less critical components. The housing components are shown individually in the Model Tree to minimize errors and simplify the overall process.

Detailed calculations for interference fits: elastic-plastic material models

In addition to a number of user-friendliness improvements, the stress hypotheses for tapered and cylindrical interference fits have also been expanded in FVA-Workbench 9. Calculations can now be performed according to the von Mises shape modification hypothesis in addition to the DIN 7190 shear stress hypothesis. This allows for the consideration of strain hardening curves to more accurately represent the material behavior during partial plastification. 

More than just software – a bridge between research and industrial practice

The FVA-Workbench enables engineers to easily visualize complex relationships, simplifies the simulation and analysis of influencing factors, and automates processes. From conception to optimization — the software offers comprehensive approaches for all phases of gearbox development. The underlying calculation methods are based on the results of cutting-edge German research and are supported by the expertise of FVA members.
