Current simulation systems for virtual automation usually ignore the simulation of cables and hoses. Cable simulations are commonly very specialized systems i.e. for laying cables in cars. Our approach adds a new aspect to the simulation of virtual automation systems by additionally simulating one-dimensional flexible objects like hoses and cables. The approach is physically-based and fast enough to work even in large automation systems. We describe the theoretical concepts for our mass-spring approach and identify the necessary physical parameters. In a detailed evaluation we measured the physical parameters and compared the form and characteristics of a real hose with the simulation as well as with a pure mathematical approach. Besides analysing the behaviour we evaluated the run-time performance to ensure real-time performance of the overall system.
