The assembly import for PTC’s Creo™ Elements/Pro software facilitates the automatic import of an assembly in an easy, fast and most of all highly reliable way. The ability of the new CAD interface to keep the structure of the assembly and to import the dependencies between the elements in the assembly permits the import of complete kinematic chains.
At the beginning of the development process, a new technical product is usually designed in PLM/CAD systems. Once the design process is finished, the original CAD data is then used for the dynamic simulation of the system in order to analyze system behavior or to find out, for instance, potential weak points e.g. with respect to control strategy prior to construction. Previously, this data had to be transferred to external CAE software manually, which was a time-consuming, error-prone process as the accuracy of the calculated inertia data from STL definitions was limited.
The new SimulationX CAD-interface automates this process. The CAD import of the SimulationX completes the new multi-body systems (MBS) modeling environment of SimulationX release 3.5 that upgrades visualization and handling of mechanical models. As already esteemed by SimulationX customers, elementary data of Creo Elements/Pro assemblies such as CAD geometry, mass, center of mass, position data, and inertia tensor can be exported for any set of selected parts thus providing most of the parameters needed for dynamic simulation. However, the essential benefit comes from the smart dependency handling. The SimulationX import tool exploits the structural information inherent in Creo Elements/Pro assemblies to be imported. Clearly, the parts will become rigid bodies in the MBS model. Moreover, axis and references frames in the Creo Elements/Pro assembly can automatically be mapped to certain types of joints or rigid links. In the event of ambiguities the engineer can modify and adjust these settings and define correct kinematic chains.
“The new SimulationX interface to Creo Elements/Pro offers SimulationX customers using Creo Elements/Pro the benefits of Creo’s leading edge design environment. On the other hand, CreoTM users can now easily integrate their mechanical and kinematic assemblies into the multi-physics SimulationX model for detailed dynamics investigation and optimization”, explains Dr. Andreas Uhlig, ITI Managing Director.
