FVA Releases FVA-Workbench 10

Offers new features for reliable gearbox design

The FVA-Workbench is a manufacturer-neutral solution for modeling, parameterization, and simulation of transmission systems. Version 10 was released on February 17, 2025, to make gearbox design even more efficient. For drive technology professionals, the FVA-Workbench is an indispensable tool for reliable modeling, calculation, and optimization of complex drive systems and transmission elements. The software bundles 50 years of research and development from the FVA expert network into a single platform, making its collected knowledge directly applicable for industrial practice.

Overview of new features:

2D Modeler: Faster and easier design changes 

The new 2D Modeler makes it possible to quickly and easily modify geometries, shafts, and positions in a single plane. This is especially useful for shaft modeling: the shaft contours can be intuitively edited and modified, which greatly simplifies design and troubleshooting. Another highlight is snap and grid functionality for efficiently adjusting component positions. For example, a rolling bearing can be moved specifically to the shaft edge – the 2D Modeler automatically “snaps” the edge of the rolling bearing to the edge of the shaft, which saves time and enables precise placement of gear elements. This makes subsequent adjustments easier than ever.

Shorter calculation times thanks to modularization of ISO 10300 calculations 

Bevel and hypoid gear load capacity calculations have been greatly accelerated. Standard bevel gear load capacity calculations are now up to 10 times faster thanks to modularization of calculations according to ISO 10300 – ideal for optimizations and automated calculations.

Advanced pitting calculations according to ISO 6336 and FVA 411 

The local pitting calculation was extended to cylindrical gears based on findings from the FVA 411 research project. This makes it possible to determine the safety factors for each point of the flank across the mesh and compare them with damage from tests or the field.

Variant generator: Easily calculate and compare variants 

The variant generator helps users to quickly calculate different gearbox variants. For example, gearing parameters or bearing concepts can be freely varied for drive optimization. The results are saved and can be easily evaluated using the new variant comparison function, allowing you to quickly find the optimum solution.

Gear skiving: Cost-effective cylindrical gear production 

The gear skiving feature enables you to generate the deviation-free nominal profile for skived cylindrical gears and to calculate the gear stresses on the tooth flank and in the tooth root. This makes it possible to precisely analyze the load capacity of cylindrical gears produced with this cost-effective manufacturing process.

Bevel gear calculations: Integration of the latest calculation kernels 

Bevel gear calculations can now be performed even more reliably with the new version of the software. New features enable more precise analysis and representation of tooth flank curvatures. Extended calculation options are also available, such as determination of the local flank fracture and optimization of parameters for special compensation surfaces, allowing for even more accurate contact calculations - even with flank modifications such as tip or end relief. Current standards, such as ISO TS 10300-20:2021 and ANSI/AGMA 2003-D19, have also been integrated into the software.

Quick Results View: Instant analysis of calculation results 

The Quick Results View makes it possible to see key results immediately after the calculation. This allows you to immediately recognize the effects of changes to your model, enabling you to quickly determine modifications and accelerating your development processes.
