Realistic parameters for dynamic simulation of composite cables using a damped Cosserat rod model

Abstract

Digital prototyping presents one of today’s biggest chances in boosting efficiency of product development in automotive industry. Handling flexible parts, such as cables and hoses, is a big challenge in this context. The software IPS Cable Simulation addresses this topic and solves the problem for a wide field of applications. To obtain reliable simulation results, a basic set of parameters describing the effective mechanical properties of the flexible parts is an essential part of the model. The development of the MeSOMICS measurement machine represents a practical solution to this need for experimental data. Additional challenges are related to dynamic simulations of vehicles in operation mode. To solve these, we introduced the durability and dynamics module as an extension to the established software. This leads to an extended set of required parameters. In order to obtain these dynamic parameters, two different experimental setups have been realized. The experiments investigate damped torsional and bending oscillations, and yield parameters that can conveniently be treated as effective viscous properties within the framework of our software.
