Our team is at your disposal for the realization of modeling and calculations on elements of mechanisms or structures.
We have more than 15 years of experience in these fields and have used very early shell and plate modeling, ideal compromise for the structural elements between the 3 types of modeling: bars / nodes, plate and 3D.
The rules for calculating the structures defined in the FEM's are based on the classical beam theory, so that the finite element modeling of the bar type is particularly adapted but the lessons learned are very limited.
As the calculation means have evolved considerably since the definition of the FEM rules, we now use the surface finite element methodology.
This methodology has numerous advantages:
These arguments presented, and the design of lifting equipments having evolved greatly over the years (less lattice structure and more box structures in particular), it is presently not very reasonable to be satisfied with simple modeling based on bar elements.
The software used is Autodesk Robot Structural Analysis Professional. We also have access to other softwares such as Ansys or Caesar.
