Coupling a DEM material model to multibody construction equipment
S.417-424Particle simulation with the Discrete Element Method (DEM) is well-established and widely used in soil dynamics related applications. The wide range of applications can be envisaged, for instance, in automotive engineering, material handling and

Standing on a common ground: a comparison of static stability approaches for pallet loading
Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

On the Design of Model Predictive Setpoint Controllers for Nonholonomic Multibody Systems
ABSTRACT Systems subject to constraints that are not integrable to position‐level constraints pose significant challenges for setpoint control. In particular, conventional linearization techniques may fail to yield controllable approximations, since certain directions of motion are only accessible through higher‐order interactions of the control inputs.

Vertical Vibration Reduction of Maglev Vehicles Using Nonlinear Model Predictive Control
ABSTRACT This work presents a novel nonlinear model predictive control (NMPC) strategy for high‐speed Maglev vehicles that explicitly incorporates mechanical suspension dynamics into the control model. Unlike conventional approaches, which often neglect the interaction between levitation magnet and car body motion, the proposed method enables ...

Symbolic Computation of the Inverse Dynamics of Elastic Joint Robots [PDF]
Efficient calculation of the inverse dynamics of robotic mechanisms serves as a basis for a variety of control schemes. Classical algorithms for rigid multibody systems do not apply when more realistic modeling is required. The computational treatment of
