Multibody Dynamics Integrated with Simulation Process and Data Management


Today, manufacturing firms are avoiding iterative and costly physical testing processes by implementing CAE tools into their engineering cycle. They only produce few or sometimes no prototypes at all and they easily test the products’ durability, noise and vibration harshness (NVH), computational fluid dynamics (CFD), and morewith these tools during the design process. Particularly in the automotive and aerospace & defense industries, virtual prototyping and testing have almost completely replaced physical testing, and a prototype is only built to validate the simulation results. One of the most widely used of these CAE tools is multibody dynamics (MBD) software, which is used heavily by automotive and aerospace manufacturers to analyze moving parts and where loads will be distributed. MBD software is used to analyze the system behavior of a product as a whole, and thus is extremely important to test when trying out a new design.


However, the benefits of MBD come with some shortcomings. When used independently of other CAE tools, it is difficult to manage the data that comes from the simulation. This is because while the test process becomes more advanced and complex, data grows bigger at the same pace. As a result, engineers managing the process become incapable of having the full traceability of the process, the file system cannot provide electronic revision control and appropriate access control mechanism, manually intensive and repetitive tasks become necessary, and many other problems occur.


To overcome these challenges MSC Software created Simulation Process Data Management (SPDM) – MBD integration. While MBD software is performing simulations, SPDM is managing the structures of simulation information including linkages between information items, attributes about information items and the information items themselves. Many different tasks related to pre-processing, solving and post-processing can be automated with this integration. With SPDM, manufacturers are able to eliminate the limitations of manual processes and make engineering processes more effective and the results more certain.
