Von Mises stress

Finally, a check of the eigen-frequencies of all parts of the machine was done to avoid any risk of resonance. ▲ ▲ Figure 9 : Cradle equivalent deformation and Von Mises stress Conclusion Thanks to EnginSoft’s expertise in dynamic simulation it was possible to obtain an accurate simulation of a huge planetary stranding machine in a short time. The results of these simulations support Mario Frigerio’s mechanical designers for the dimensioning of the machine. On this large machine no mistake is acceptable. Virtualisation allows saving time in the development process and is an alternative to the classical approach, in particular when historical data, from similar applications, is not available. This collaboration between companies made it possible to optimise the design of this challenging project and preserve the high quality level and performance of Mario Frigerio’s products. n This article contains references to the following products, which are trademarks or registered trademarks of their respective owners: ANSYS Workbench; RecurDyn .
