TechBlog #20 | Rolling bearing calculations with consideration of geometric deviations

Geometric deviations of bearing raceways have a significant influence on the key characteristics of rolling bearings, such as the lifetime. The FVA-Workbench allows users to directly consider geometric deviations in bearing design. User-defined calculation routines can be implemented with little effort via the integrated scripting interface.

TechBlog #19 | Lenze relies on the FVA-Workbench for technical sales

As challenges increase across the mechanical engineering sector, it is essential to be able to rely on capable partners where necessary and focus on core competencies. With the FVA-Workbench, Lenze has a powerful tool for quickly and easily performing all gearbox development tasks. The high level of automation is crucial for productivity and makes it possible to use calculations in sales discussions.

TechBlog #18 | REXS at ZF

The REXS standard interface has been developed since 2017 on behalf of FVA (Forschungsvereinigung Antriebstechnik e.V.) under an open source license. In the process, the requirements of the world’s leading powertrain and suspension technology company, ZF Friedrichshafen AG, played a decisive role in shaping REXS.

TechBlog #17 | Planetary Gear Unit Design with the FVA-Workbench

STÖBER Antriebstechnik GmbH + Co. KG rely on the FVA-Workbench for dimensioning and verification of their drives. The calculation and simulation software allows STOBER engineers to develop their innovative gear unit solutions more quickly and efficiently. The result: higher quality products.

TechBlog #16 | Consideration of Load Spectra in Transmission Design

For optimal gear design in accordance with requirements, it is essential to consider load spectra under the most realistic conditions possible as early as the virtual basic design phase. This is the only way to ensure that all components are loaded as evenly as possible to avoid overdimensioning.

TechBlog #15 | Practice-Oriented Determination of the Longitudinal Load Distribution of Planetary Stages

The goal of increasing the power density of a gear unit demands that extraneous material reserves can be detected and reduced to the necessary level. In this context, it is important to know the influences acting on the gear unit and the resulting loads. Precise knowledge of the longitudinal load distribution in the gear meshes during operation, and specification of suitable microgeometries for its optimization, play a decisive role.

TechBlog #14 | The Influence of Wheel Body Rim Width on Longitudinal Load Distribution

The influence of the wheel body design and the required modification on the longitudinal load distribution are demonstrated, using an example two-stage reduction gearbox as commonly used in electromobility. The influence on the load and pressure distribution are also analyzed.

TechBlog #13 | Easy exchange of gearbox data with REXS

The new version 1.4 of the REXS standard creates a common, comprehensive, and open description for gearbox structures.

TechBlog #12 | Formula Student Team Develops Winning Drive with FVA-Workbench

The software enables the KA-RaceIng team of the international engineering competition to perform fast, research-based gear design with One-Click FEM design features.

TechBlog #11 | Bevel Gear Wheel Body Design

Basics of bevel gear calculations in the FVA-Workbench

TechBlog #10 | Influence of the Load-Dependent Center Distance

Automatically consider the load-dependent center distance with the FVA-Workbench.

TechBlog #9 | Reports in the FVA-Workbench

A New Approach to the Preparation and Interpretation of Calculation Results

TechBlog #8 | Accurate Prediction of Damage Over the Operating Life of Bevel Gears

Calculation methods for bevel and hypoid gears in the FVA-Workbench.

TechBlog #7 | How bearing selection influences gear modifications

Crucial in gear development: the selection of rolling bearings already influences the required gear corrections.

TechBlog #6 | The Influence of Rolling Bearing Profiling on Rigidity

Detailed calculation of rolling bearings in the FVA-Workbench, based on consideration of the profiling of roller bearings.

TechBlog #5 | Local bearing capacity vs. standardized methods.

Learn about the advantages of the extensive local bearing capacity approaches of the FVA Workbench compared to standardized methods.

TechBlog #4 | The Influence of Bevel Pinion Retractability on Casing Design

The bevel gear stage helps to determine how the housing must look. In particular, it must be ensured that the pinion can be pushed into the bevel gear stage. The solution: drawability calculation.

TechBlog #3 | FE Shaft Calculations with the FVA-Workbench

Not all bodies can be analytically described with sufficient accuracy. For this reason, casings, planet carriers, wheel bodies, and shafts in particular are considered using finite element analysis in the FVA-Workbench.

TechBlog #2 | REXS Version 1.3 Published

Free exchange format for gearbox data: REXS Version 1.3 offers a number of enhancements for various gearbox machine elements. A total of 19 feature and change requests from industrial companies and CAE tools developers have been implemented.

TechBlog #1 | Designing low-noise gears

Vibrations can be detected as noise, and may also lead to component fatigue and cost-intensive damage. These undesirable effects can already be avoided in the design phase by analyzing and optimizing the excitation behavior of the gearbox.
