MSSKW

Efficient modeling and simulation of stochastic influences on structure-borne sound propagation in waveguides

In many technical applications, knowledge of mechanical wave propagation in one-dimensional structures is essential. This project specifically focuses on multi-wire twisted cable structures, as the mechanical vibration behavior is still poorly understood in the scientific community due to the complex contact and friction situations between the individual wires. To date, no models exist that can predict the eigenfrequency behavior in the kHz range in the frequency domain.

The goal of the MSSKW project is to estimate mechanical wave propagation using new mathematical approaches from the field of unparametric uncertainty quantification. Instead of the complex mechanical deterministic modeling of the cable, stochastic models of the cable's stiffness and damping properties are used. Based on a "good" deterministic model, stochastic approaches will be developed to represent the various unknown influences.
