Integrated modeling, simulation, and optimization of multibody systems
(1994) Eberhard, Peter; Bestle, Dieter
Design of nonlinear dynamic systems is a challenging task. Computers may help to analyze and optimize virtual prototypes in an earl design phase, but there is a lack of design tools. In this paper, a design concept on the basis of a multibody system approach is described. Programs for modeling, simulation, sensitivity analysis, optimization, and animation are operating under a common administration which ensures model consistency. The designer is supported by a graphical user interface, distributed computation improves efficiency.

Optimal damping of multi-story buildings under wind excitation
(1994) Bestle, Dieter; Schiehlen, Werner
Wind excited vibrations of high-rise buildings can be reduced by installing additional damping devices like tuned mass dampers. The design of tuned mass dampers on different levels of the building is performed via a computer-aided modeling and design approach. A multi body system model is used for describing the dynamic behavior of the structure and the problem of optimizing the parameters of the damping devices is formulated as a nonlinear programming problem. An application to a building of the University of Stuttgart shows that optimal designs with minimal accelerations of the building can easily be obtained.
