ABSTRACT
A typical wiring harness network of a modern passenger car contains about 1.5 km of cables, each of them a composite structures itself, and most of them taped together to cable bundle segments, in altogether several hundred variants. During production, all this has to be assembled into the car body, to more than 90% by human workers rather than robots, since such cable systems are topologically complex slender flexible structures whose spatial deformation behavior is still too complicated to be handled by robots.
Since more than two decades, all car manufacturers try to virtualize their product development as well as manufacturing and production processes. To support this with suitable simulation tools requires mastering of a wider range of areas in an interdisciplinary manner. Industrial applications like geometrical design, construction of single parts up to the whole product, assembly planning, digital validation of component or system functionality, up to virtual training of workers to handle (eventually robot assisted) manufacturing tasks, and in the same context perform an ergonomic assessment of working tasks to improve workplace design, cannot be covered by simulation solutions developed from methods within a single academic domain.
In the presentation, an outline will be given how this challenge is addressed at Fraunhofer ITWM by the development of solutions incorporating methods from areas like numerical and experimental structural mechanics, software engineering, computer graphics, ergonomics and human factors engineering, as well as, last but not least, mathematical methods and computational algorithms from state of the art industrial mathematics.
