Abstract In modern high resolution optical systems like astronomical telescopes or lithographic objectives, performance degradations can be caused by various disturbances. Holistic system simulation is required to predict the precision systems. this paper a method for transient dynamical-thermal-optical modeling and introduced. Thereby, elastic deformation, rigid body motion, mechanical stresse...

Methods are developed for describing and manipulating symbolic data objects that are useful for analyzing the kinematics and dynamics of multibody systems. These symbolic objects include 1) vector/dyadic algebraic expressions, 2) physical components in a multibody system, and 3) program structures needed in a numerical simulation code. A computer algebra language based on these methods encourag...

This chapter provides a general description of a variational graph-theoretic formulation for simulation of flexible multibody systems (FMS) which includes a brief review of linear graph principles required to formulate this algorithm. The system is represented by a linear graph, in which nodes represent reference frames on flexible bodies, and edges represent components that connect these frame...

This paper deals with a first implementation of the socalled motor calculus within Modelica. The motor calculus can be used to describe the dynamical behaviour of spatial multibody systems in an efficient way. This method represents an alternative approach to modelling of multibody systems. In the paper, some fundamentals of motor calculus are summarized. Furthermore, a simple implementation of...

The increase in processing power and the theoretical breakthroughs achieved in multibody systems dynamics have improved the usefulness of dynamic simulations to such an extent that the development of a whole range of applications has been triggered. Dynamic simulations are used for the analysis of mechanisms, virtual prototyping, simulators, computer animation, advanced control, etc. and are ga...

In this paper we address the role of multibody interactions for the coarse-grained approximation of stochastic lattice systems. Such interaction potentials are often not included in coarse-graining schemes, as they can be computationally expensive. The multibody interactions are obtained from the error expansion of the reference measure which is, in many cases, chosen as a Gibbs measure corresp...

Deformable components in multibody systems are subject to kinematic constraints that represent mechanical joints and specified motion trajectories. These constraints can, in general, be described using a set of nonlinear algebraic equations that depend on the system generalized coordinates and time. When the kinematic constraints are augmented to the differential equations of motion of the syst...

Mechanical Dynamics Inc. has entered its twenty-sixth year of producing ADAMS® (Automatic Dynamic Analysis of Mechanical Systems), the world’s leading commercial mechanical analysis software for kinematics and dynamics of multibody systems. During the past twenty-five years, use of mechanical analysis software has grown dramatically. No longer the province of a fringe group of highly trained sp...
