The selection of the contact force model plays a crucial role in the modeling and analysis of
dynamical systems. The seminal work by Hunt and Crossley, published in 1975, is one of …

A novel normal contact force model considering the energy dissipation for viscoelastic
bodies is presented. By solving the differential equation through applying Laplace transform …

This investigation aims to analyze the underlying relationship between the dynamic dashpot
and the static force-displacement models used in multibody systems. By ignoring the plastic …

We present a simulation framework for multibody dynamics via a universal variational
integration. Our method naturally supports mixed rigid-deformables and mixed …

The discrete element method (DEM) is widely used for the simulation of ballast behavior
under static and dynamic loading conditions. Due to the irregular shape of ballast particles …

This paper presents a methodology for the fast, parallelized simulation of the bouncing
deployment of lander/rover probe to an asteroid or comet. The target asteroid or comet is …

Deflector wheel classifiers are widespread in industry for the separation of powders into fine
and coarse powders. Even though this separation process has been known for quite some …

In this study, the effects of contact force modeling parameters, which included the particle–
particle friction coefficient (A), spring constant (B), ratio of the tangential spring constant to …

A detailed system dynamics model is essential for the design and calibration of the system
controller. This paper introduces a control-oriented full dynamic model for the dog clutch …

Various special effects occur during the operation of vibratory conveyors, eg, multiple
feeding velocities at the same excitation amplitude or so-called microthrows. In this work, a …
