Model Order Reduction of a Sliding Beam using a Global Basis: Formulation and Evaluation
Sebastian Weyrer, Johannes Gerstmayr, Aki Mikkola +1
Model order reduction decreases the dimension of a mechanical system by introducing modal coordinates that retain important dynamic characteristics. Sliding beams, as found in tele…
Towards Reinforcement Learning Based Log Loading Automation
Ilya Kurinov, Miroslav Ivanov, Grzegorz Orzechowski +1
Forestry forwarders play a central role in mechanized timber harvesting by picking up and moving logs from the felling site to a processing area or a secondary transport vehicle. F…
Real-Time Structural Deflection Estimation in Hydraulically Actuated Systems Using 3D Flexible Multibody Simulation and DNNs
Qasim Khadim, Peter Manzl, Emil Kurvinen +3
The precision, stability, and performance of lightweight high-strength steel structures in heavy machinery is affected by their highly nonlinear dynamics. This, in turn, makes cont…
Data-driven simulation for general purpose multibody dynamics using deep neural networks
Hee-Sun Choi, Junmo An, Jin-Gyun Kim +5
In this paper, a machine learning-based simulation framework of general-purpose multibody dynamics is introduced. The aim of the framework is to generate a well-trained meta-model…
