: When Stress & Strength GmbH was established in May 2000 as a spin-off of Fraunhofer LBF
in Darmstadt it was able to draw on many years of expert experience in structural durability research.
: Based on research of Fraunhofer LBF, the first software was published in 2001, which was LBF®.WheelStrength for CAE Patran/Nastran; however it was not yet integrated into CAE at this time, nor was there an individual user interface.
: The company expanded the software release with a further CAE interface for ANSYS.
: Both versions were enhanced and expanded using various bug fixes and feature releases. Different solutions for client-specific problems were also developed.
Head office of Stress & Strength GmbH in Darmstadt.
: The increasing digitalisation of production processes in the automotive industry also placed higher demands on the software, thus work began on new LBF®.WheelStrength Version 3.0.
: The new software LBF®.WheelStrength 3.0 was successfully released. New features included an individual user interface, new functionalities for passenger cars and commercial vehicles, as well as various tire models.
: Based on LBF®.WheelStrength 3.0 the first release of a new generation was published under the name LBF®.WheelStrength Cordelia with once more extended functionalities.
: The successor of LBF®.WheelStrength Cordelia was successfully released: LBF®.WheelStrength Ophelia. This release is mainly characterized by its increased performance and efficiency and thereby saving of calculation time.
: LBF®.WheelStrength Bianca offers a new powerful graphic module, an additional interface and a tire model extension. The development on new features and the increase of processing speed could be continued successfully.
: LBF®.WheelStrength Ariel provides further options to customize the calculation for specific demands. Increased functionality and optimized graphic processing enhance the evaluation of the simulation results.
: With the current release LBF®.WheelStrength Titania the functional range is extended by another stress hypothesis and a design spectrum for the lifetime assessment of wheels and wheel hubs on 3-axle semi-trailers. Besides the interfaces to Abaqus, ANSYS, Nastran and Permas, an interface to Altair Hyperworks OptiStruct is now available.
: LBF®.WheelStrength Miranda
adds the possibility to define a preload, that is super imposed with the standard loads. There is also a new design spectra for torsion, that adds the load cases braking, braking in curve and acceleration. In a new menu you can calculate the distance between two nodes. The length of the load application has been reduced drastically.
