Here we present three current versions of calculation software for the design, optimization, and development of drive components.

GWJ Technology: Extended Functions for the Design of Drivetrains

GWJ Technology presents the new version of its System Manager, which serves as an extension for the E-Assistant and TBK calculation solutions. With numerous innovations and optimizations, the software offers engineers enhanced options for modeling, calculating, and analyzing complex drive systems.

A significant advancement is the integration of shaft-hub calculations for keyway, interference fit, and spline connections. This allows calculations and data to be managed and exchanged directly within the system using the corresponding individual modules. The E-Assistant and TBK individual modules can be opened directly within the system environment. Additionally, a new notification window provides greater transparency, as notes and results from the system calculation, as well as from the rolling bearing, gear, and shaft-hub calculations, are displayed centrally.

The operation has also been optimized: A switch is now available in the status bar that enables automatic recalculation after each input change. All results are updated immediately, allowing users to instantly see the effects of parameter changes.

FVA-Workbench: New Functions for Efficient Gearbox Design

The new version 10.1 of the FVA-Workbench is now available. It offers numerous new features and improvements that enhance the modeling, calculation, and optimization of complex drive systems: the plain bearing calculation has been expanded in several areas. New example models are available in Easy Entry. Mixed friction and wear can now be calculated. The tilting pad stiffness can be defined via an FE model, a contact model, or manually. Additionally, the input of temperature boundary conditions has been simplified. Geometry can now be calculated based on two-flank tools. Local stresses can be determined according to FVA 30 and FVA 377 (FEM). Furthermore, a gear meshing animation and CAD export are now available. The material and component database has been significantly expanded. CO₂ emissions from gearbox losses can now be directly recorded in the model, taking into account emission factors in accordance with the VDA report "Emission factors for electricity, district heating, and fuels."

Kisssoft: For Optimized Design Analyses

Parametric studies are an integral part of engineering calculations. In this process, specific parameters in the model are deliberately varied to analyze their impact on the calculation results. Parametric analyses are typically performed using programming languages. Kisssoft supports parametric analysis through its own integrated scripting language as well as a COM interface that is compatible with common programming languages such as Python, Visual Basic, and others.

In Kisssoft, the new special function SetElementData (elementName, parameterName, newValue) has been added to the already available script variables and COM interface variables, allowing the variation of shaft geometry, forces, and bearings. This extension simplifies the variation of arbitrary parameters in the shaft model. A typical application example is analyzing the impact of bearing position, bearing clearance, or preload on rolling bearing lifespan. The results can be written to an external file and easily integrated into third-party applications.
