Theoretical modeling and numerical solution methods for flexible multibody system dynamics
TL;DR: The research status of modeling methods of flexible MSD in recent years is summarized, including the selection of reference frames, the flexible body’s kinematics descriptions, the deductions of dynamics equation, the model reduction techniques and the modeled methods of the contact/collision, uncertainty and multi-field coupling problems.

Dynamic response and sensitivity analysis for mechanical systems with clearance joints and parameter uncertainties using Chebyshev polynomials method
TL;DR: In this paper, an analysis method for dynamic response and parameter sensitivity of mechanical systems is proposed with the consideration of both clearance joints and uncertainties, where elements of a revolute clearance joint are modeled as colliding bodies, where continuous contact force model and modified friction force model are employed to describe the impact-contact behavior.

Design optimization of dual-axis driving mechanism for satellite antenna with two planar revolute clearance joints
TL;DR: The results show that the acceleration peaks of satellite antenna and contact forces in clearance joints are reduced obviously after design optimization, which contributes to a better performance of the satellite antenna.

Coefficient of Restitution Interpreted as Damping in Vibroimpact
K. H. Hunt,F. R. E. Crossley +1 more
TL;DR: In this paper, the Kelvin-Voigt model is shown to be logically untenable, for it indicates that the bodies must exert tension on one another just before separating, and it denotes that the damping energy loss is proportional to the square of the impacting velocity, instead of to its cube.

A Contact Force Model With Hysteresis Damping for Impact Analysis of Multibody Systems
TL;DR: In this article, a continuous contact force model for the impact analysis of a two-particle collision is presented, where a hysteresis damping function is incorporated in the model which represents the dissipated energy in impact.
Journal ArticleDOI
Literature survey of contact dynamics modelling
Gabriele Gilardi,Inna Sharf +1 more
TL;DR: An overview of the state of the art on impact and contact modelling methodologies, taking into account their different aspects, specifically, the energy loss, the influence of the friction model, solution approaches, the multi-contact problem and the experimental verification is provided.

Why the Monte Carlo method is so important today
TL;DR: The reasons why the Monte Carlo method has evolved from a ‘last resort’ solution to a leading methodology that permeates much of contemporary science, finance, and engineering are explored.

Compliant contact force models in multibody dynamics : evolution of the Hertz contact theory
TL;DR: In this paper, the main issues associated with the most common compliant contact force models of this type are analyzed in terms of the dynamic simulations of multibody systems, which allow for the comparison of the similarities and differences among the models considered.
