The tension chording principle is a biomimetic lightweight design principle for kinematic chains. A great number of conceivable actuation concepts exist for specific applications that use the tension chording principle. Their effect on the system weight cannot yet be evaluated without calculating structural stress and movement. When comparing the effects on system weight of different actuation concepts, modelling the concepts can be time-consuming. We present an approach that uses a modeling system combining multibody and finite element simulation. Thus, stress and movement are calculated in the same model. We successfully test the approach for a simple system.
