Structural Models for Wind Turbine Design Wind Drivetrain Conference2022

NB 2023-02-21

We are pleased to invite you to watch Stefan Dietze's presentation that he held at the 5th Wind & Drivetrain Conference on April 6, 2022.

@SD's mission is to explore and make available new multi-scale physics for structures and motion simulation, to maintain and expand existing technology. Stefan leads the team flex body analysis, which contributes to the Abaqus and the Simpack solver..

Before the acquisition of Simpack AG by Dassault Systèmes in 2014 Stefan was responsible for product management, customer support, and training for flexible bodies in the multibody system code Simpack. In 1999, he received a Ph.D. in Aerospace Engineering.

Abstract:

In contrast to high-resolution finite element methods, a strength of multibody system models is the description of the complex mechanical systems with a comparatively small number of degrees of freedom, which leads to a low computational effort. This is necessary for the analyses of multiple design variants. Different levels of modeling fidelity enable the optimum balance between computation time and depth of results to be achieved. Beam models are the obvious choice for modeling the flexibility of rotor blades in early design phases. The presentation covers the recent enhancements of composite beam models in Simpack and Abaqus. For a wide range of components where the assumption of small deformation and a linearized material law is sufficient, the modeling workflow starts with the generation of a reduced finite element model. A number of such models can now be assembled into a single linear flexible body, which improves the handling and reduces the computation effort of a modular database. The presentation will also cover the preparation of linear flexible bodies in the structures apps of the 3DEXPERIENCE platform.
