System Calculation Enhanced With New Features

GWJ Technology GmbH from Braunschweig, Germany, a leading manufacturer and provider of calculation software for the mechanical engineering, recently introduced a new version of its system calculation “SystemManager“.

SystemManager is an extension to the web-based calculation software eAssistant (web solution) and TBK. eAssistant and TBK have been around for many years now and are among the most popular software solutions in the business today. SystemManager is a true software application for complete systems of machine elements, i.e., the software is a coupled FE calculation of multi-shaft systems with gears as non-linear coupling elements.
The new version provides an alternative method of importing and automatically meshing housings and planet carriers. This offers an even better mesh quality and allows a meshing of very complex geometries, for example the geometries of gearbox housings in automotive applications are known to be very complex.
The system calculation considers now rotating 3D elastic parts for the calculation of eigenfrequencies (e.g., of planet carriers) using modal reduction.
Coupling connections were added in addition to the previous connection types cylindrical gears, planetary gear trains, bevel gears, worm gears and belts. It easily allows to consider hydraulic or electric connections between subsystems.
Many small extensions had been added like splitting or merging shafts in addition to copy, shift or mirror options. All bearings types are now drawn with separated inner and outer rings in 2D and 3D views. The animations for 3D mode shapes therefore allow a better understanding of the movement in the bearings.
Graphics can be frozen inside the program to allow comparisons and a copy option using the system clipboard was added for graphics for quicker transfer into other documents. The default format for reports is now PDF/A instead of standard PDF. The software documentation is now available as context sensitive help allowing faster access of information to certain inputs.
There are other new additions to the integrated bearing calculation.
