VMAP for Full Model Management and Flexible CAx Workflows
VMAP enabled multi-disciplinary collaboration on jet engine design
We present applications of the VMAP Standard in the field of gas turbine aero-engines. The utilization of VMAP enables the transition from conceptual/preliminary design to higher fidelity design in a sustainable and scalable way. After providing information on the context of engine development at DLR, we elaborate on concrete use cases of VMAP. Read more here...
Semantic concepts to store and access VMAP-based simulation data
Integrating physical simulation data into data ecosystems challenges the compatibility and interop-erability of data management tools. Semantic web technologies and relational databases mostly use other data types, such as ERP or design data.
VMAP as an industrial standard offers novel possibilities when compared to other standardization approaches such as the archival-oriented ISO standard STEP (ISO 10303 “Standard for the Ex-change of Product model data”). While the latter has included simulation data in its CAD modules, this has not proven feasible in industry contexts. On the other hand, enhancing VMAP with seman-tic capabilities promises to finally bridge the gap between product and simulation data manage-ment (PDM and SPDM). Read more here...
The application of the VMAP Standard in virtual process chains for continuous fiber reinforced polymers
Distinguished by their exceptional weight-specific mechanical properties, continuous fiber reinforced polymers (CoFRP) stand out as ideal materials for use in load-bearing components within the automotive and aviation sectors.
The macroscopic composite properties are determined by a multi-step manufacturing process. This typically involves an initial draping step, followed by the infiltration of liquid resin, and the thermo-chemical curing reaction within the mold. Depending on the component’s shape, process parameters, and boundary conditions, significant variations in local fiber directions and constituent composition may arise within the part, leading to global and local deviations from nominal mechanical material properties.

Standardized simulation workflows in the automotive industry
Today, products of a certain complexity must meet a wide range of functional requirements. This is reflected in the current virtual development process. The simulations of the different engineering disciplines are carried out in parallel and in certain cases also sequentially. In this case, the output of the previous simulation is often the input for the subsequent simulation. An example for this is forming simulation, which leads to internal stresses and changes in sheet thicknesses. This material progression has a significant impact on the results of NVH or strength simulations. Read more here...
