Cables, Hoses and Flexible Structures

We develop software for the simulation of flexible cables, hoses, and flat components in vehicles or systems. In this way, we support companies in virtually planning assembly processes, predicting component deformation during operation, and solving individual problems.

For the simulation of cables and hoses, we are developing the commercial software tool IPS Cable Simulation together with fleXstructures GmbH, IPS AB, and the Fraunhofer-Chalmers Centre. Our models are based on innovative approaches from discrete Lagrangian mechanics and discrete differential geometry. Using discrete Cosserat rods, we calculate the deformation of cables and hoses interactively, in real time, and in a physically realistic manner.

Determining Modell Parameters and Early Detection of Operational Problems

However, even the best modeling cannot deliver good simulation results without high-quality input data. It is therefore important to provide realistic mechanical properties of cables and hoses – quickly and robustly. The MeSOMICS^® measuring machine developed by us offers the optimal solution for this.

We go beyond pure assembly planning: even during virtual product development, we identify potential Operational Problems and Test Solutions. To do this, we analyze vibration dynamics and NVH (Noise, Vibration, Harshness), examine the interaction with flexible clips and holders, and predict the service life of cables under realistic installation conditions.

More complex simulations, which represent more physical effects, often require more complex Parameter Acquisition. That is why we are continuously developing new constitutive models, experimental methods, and evaluation techniques. With our parameter estimators, we can quickly provide reliable mechanical properties even for pipes that have not yet been measured.

Focus on Flexible Flat-Surface Components

In addition to cables and hoses, many flexible flat components must also be handled in vehicles, from small Ribbon Cables and Bellows to large interior trim panels. We also develop special solutions for these structures. Some of our methods have already been incorporated into commercial products such as IPS Bellows and Grommets and IPS Flat Cables.
