Dynamic Response Optimization of Complex Multibody Systems in a Penalty Formulation Using Adjoint Sensitivity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multibody dynamics simulations are currently widely accepted as valuable means for dynamic performance analysis of mechanical systems. The evolution of theoretical and computational aspects of the multibody dynamics ...
Direct and Adjoint Sensitivity Analysis of Ordinary Differential Equation Multibody Formulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sensitivity analysis of multibody systems is essential for several applications, such as dynamicsbased design optimization. Dynamic sensitivities, when needed, are often calculated by means of finite differences. This ...
Motion Planning of Uncertain Ordinary Differential Equation Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents a novel motion planning framework, rooted in nonlinear programming theory, that treats uncertain fully and underactuated dynamical systems described by ordinary differential equations. Uncertainty in ...
Singular Vector Analysis for Atmospheric Chemical Transport Models
Publisher: American Meteorological Society
Abstract: The singular vectors of a chemical transport model are the directions of maximum perturbation growth over a finite time interval. They have proved useful for the estimation of error growth, the initialization of ensemble ...
Computation of Direct Sensitivities of Spatial Multibody Systems With Joint Friction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Friction exists in most mechanical systems and may have a major influence on the dynamic performance of the system. The incorporation of friction in dynamic systems has been a subject of active research for several years ...
