LMS Virtual.Lab System-Level Fatigue
LMS Virtual.Lab System-Level Fatigue offers a complete solution for optimizing subsystems or assemblies, and analyzing their strength and fatigue. It allows engineers to calculate component loads from prescribed system motion through multibody simulation, using the embedded LMS Virtual.Lab Motion solver. These component loads are combined with structural stresses. Finally, material fatigue parameters are applied to predict the component fatigue hotspots and corresponding fatigue life.
Its easy-to-use interface with dedicated templates and customized wizards facilitates multibody model set-up. Scalable modeling makes it possible to refine models at any time and work with rigid or flexible component representations. The previously lengthy and error-prone job of integrating a flexible body now only takes a few mouse clicks. All the user needs to do is pick up the component FE mesh and drag it into the system model. All body connections are automatically established based on detected attachment nodes and degrees of freedom.
LMS Virtual.Lab System-Level Fatigue cascades road profiles down to load responses on the component level. The multibody model is put on a virtual test rig and appropriate boundary conditions for the road profile are automatically set. For each individual system part, predicted information on dynamic load cases, modal participation factors, excitation locations and local axes configurations are automatically transferred to the fatigue-life solver.
The post-processing functions provide fast and critical insights into the load transfer path for the fatigue life of any component. This allows engineers to quickly investigate hotspots and rerun analyses for numerous system-level design variants.
