    Collocation Methods for the Investigation of Periodic Motions of Constrained Multibody Systems

    The investigation of periodic motions of constrained multibodysystems requires the numerical solution of differential-algebraicboundary value problems. After briefly surveying the basics of periodicmotion anal...

    A posteriori error control in radiative transfer

    This note introduces a finite element approach for a radiative transfer model equation which allows for a posteriori error control and thus opens up the way for adaptive grid refinement strategies. Apart from ...

    Stabilized multistep methods for index 2 Euler-Lagrange DAEs

    We consider multistep discretizations, stabilized by β-blocking, for Euler-Lagrange DAEs of index 2. Thus we may use “nonstiff” multistep methods with an appropriate stabilizing difference correction applied t...

    The Drazin inverse in multibody system dynamics

    The numerical analysis of multibody system dynamics is based on the equations of motion as differential-algebraic systems. A thorough analysis of the linearized equations and their solution theory leads to an ...

    Constrained Mechanical Systems in Descriptor form: Identification, Simulation and Control

    The subject of constrained controlled mechanical (“mechatronic”) systems in descriptor form is a field of current research in mechanical engineering, control theory and applied mathematics. It is essentially b...

    The Benefits of Parallel Multibody Simulation and its Application to Vehicle Dynamics

    In summer 1987 most of the multibody dynamics community met at the JPL, Pasadena, to discuss the needs and the open problems in multibody system simulation, especially for space applications. P. W. Likins stat...

    Numerical solution of differential-algebraic equations for constrained mechanical motion

    The two most popular formulations of the equations of constrained mechanical motion, thedescriptor andstate-space forms, each have severe practical limitations. In this paper, we discuss and relate some proposed ...

    A New Class of Generalized Inverses for the Solution of Discretized Euler — Lagrange Equations

    For a wide class of mechanical systems, so-called multibody systems, there are highly developed methods for the automatic generation of the corresponding equations of motion. As these equations can be stated in v...

    Kompressionsverhalten isotroper Pulvermischungen

    The three hyperbolic constants a, b and C were interpreted for the compression equation (s − a) (p + b) = C. Their dependence upon the mixture ratio of two substances was investigated. The quantity b was desig...
