Simulation von Schwingungssystemen mit Analogrechnern
A 22-page technical paper by Dr. H. Kramer (Staatliche Ingenieurschule Konstanz), contributed to a VDI-Bildungswerk course (Dusseldorf 1969) on solving control and vibration problems with industrial and self-built analog computers. Part I covers qualitative and quantitative analog simulation of linear spring-damper-mass oscillators, including time and amplitude normalization, maximum-value estimation under initial-condition, step, and periodic forcing, and generation of undamped oscillations. Part II treats nonlinear and continuous systems: the mathematical pendulum (small and large deflections), oscillators with nonlinear damping and bistable restoring forces, two-mass systems, and modal simulation of a jumping beam.
