Abstract

In high-precision complex mechatronic devices, specifications are mostly affected by the contribution of several disciplines. Thus, in order to facilitate the fulfilment of the specifications, it is crucial to have a well-defined requirement for each sub-system during the entire design process. Model based system engineering (MBSE) is a multidisciplinary approach with the aim of developing a balanced system solution in response to various stakeholder needs.
A multibody dynamics model is developed to break down specifications from system to sub-system level. An analysis of the impact of the motion of a 2 DOF mechanism is done. Special focus is given to the location and impact of the interaction between the Center of Gravity and Center of Stiffness to the reaction forces. The derived sub-system requirements can then be used as an input for mono-disciplinary early concept design.
