Siemens expands simulation capability for electrification and aerospace design with Simcenter mechanical solutions
The latest release of Simcenter software from Siemens for mechanical simulation helps streamline electrification engineering projects, assists new aircraft to meet margins of safety and simplifies durability testing across many industries.
“Addressing complex engineering challenges such as developing products that are more powerful, yet greener, lighter yet stronger requires a fully-integrated CAE solution,” said Jean-Claude Ercolanelli, Senior Vice President, Simulation and Test Solutions, Siemens Digital Industries Software. “The latest release of Simcenter offers a host of powerful enhancements to help engineers meet those challenges efficiently and significantly faster than ever before, whether that is getting tyre contact simulations solved 45% more quickly or reducing airframe structure pre-processing by up to 80%.
3D Printing
For those exploring Additive Manufacturing (AM), build process simulation is a must, particularly when dealing with metals-based powder-bed fusion production methods. The complex nature of these processes usually require the AM engineer to collaborate with an experienced CAE expert. The latest release of Simcenter 3D software introduces a simplified application for simulation of the powder-bed fusion (PBF) build process that is easy to use for engineers without in-depth CAE expertise. Using a robust voxel-based mesh in the background, it can quickly model and simulate the PBF build process, allowing engineers to gain a good understanding whether a part will build successfully. More detailed analysis can then be performed by CAE experts also using Simcenter 3D, thus enhancing collaboration.
Following on from the introduction of the ability to launch simulations on remote HPC systems directly from within Simcenter 3D, engineers now have the ability to review simulation results directly from the Remote Simulation interface. This helps engineers determine if simulation studies ran correctly before transferring large results files back to a local workstation for in-depth evaluation.
Electrification
Electrification is a major trend across the Automotive industry and development of new Electric Vehicle (EV) powertrains tend to be broken into silos for e-motor design, transmission analysis, NVH and acoustics. Simcenter mechanical simulation tools can help automotive manufacturers break these silos by helping critical load, design and model information to flow easily between each of these disciplines for EV powertrain development. Beyond EV development, additional new capabilities in this release improve simulation of other automotive applications from NVH, to tires, to windshield wiper performance.
The new contact pattern display in Simcenter 3D helps analyse wiper contact patterns. By modeling the wiper as a flexible body combined with contact elements, the new contact pattern display will show easy to interpret results of the wiper forces across the windscreen, allowing the user to learn how consistently or inconsistently the forces are distributed and if the wiper design is working as expected, without the need for costly and time-consuming physical testing.
Finally, the Tyre modeling software has an updated road contact algorithm to reduce the large amount of road data exchange required to build the high-fidelity tyre models required for driving simulators and Hardware-in-the-Loop set-ups. This means that computational performance is increased by up to 45% enabling the use of high-fidelity tyre models in real-time applications.
Aerospace
For the Aerospace industry, new capabilities reduce the number of models needed to simulate the behaviour of thin aircraft skins and perform margin of safety calculations more quickly than ever before. In addition to the new improved airframe applications, Simcenter can help engineers better understand rocket launch dynamics by simulating the liquid sloshing in fuel tanks.
New standard calculation templates have been added to the margin of safety analysis tools within Simcenter 3D. These new templates automatically prefill all the inputs based on a set of rules so the engineer just needs to select the geometry to apply calculation to – removing the traditional reliance of custom script development and the associated maintenance costs.
A new capability in Simcenter Nastran software helps airframe engineers with thin skinned airframe structures that have different stiffness behaviour depending on the load case; tension (membrane) vs. compression (shear). Today, engineers typically create multiple models and properties to account for all the different loading conditions. The new tension-only-quad will change from membrane behaviour to shear behaviour automatically so only a single model is needed to represent an airframe structure – reducing simulation preprocessing time by up to 80%.
While not isolated to aerospace and rocket applications, liquid fuel sloshing dynamics in storage tanks can pose a challenge to guidance systems. In Simcenter Nastran, the new incompressible fluid model helps to predict slosh frequencies and hydro-elastic modes. In other industries, it can also be used for evaluating sloshing in cargo, ballast or fuel tanks of large ships and automotive vehicles.
Industrial Machinery
For the Industrial Machinery industry, machine uptime is the prime driver, but machine manufacturers often lack the time or resources to physically test their machines to their limits. Here, Simcenter can help with new capabilities to help durability prediction without the need for specialist knowledge.
Simcenter 3D overcomes the need for separate toolsets and knowledge for proper durability by streamlining and automating strength analysis. Simcenter 3D can automatically calculate the parameters needed to adhere to the industry standard FKM guidelines. This means engineers can conduct durability analysis directly from their stress analysis results, to ultimately help machines meet operation requirements.
Industrial power transformers need to meet strict noise emission standards and qualify the EMAG-Acoustics models for transformer development. Simcenter 3D can now simulate the complex multi-disciplinary magnetostriction effects that cause transformer noise very quickly and accurately. Additionally, the forces calculated can be used both for noise and vibration assessment allowing electromagnetics and acoustic performance simulation within a single environment.
Lastly, industrial machines often have rotating shafts spinning at high speeds which can also vibrate. Engineers use rotor dynamics simulation and Campbell diagrams to understand the vibration frequencies at various operating speeds – but these are only applicable to linear systems. When working with non-linear bushing systems, Simcenter 3D allows the calculation of complex modes during a nonlinear harmonic response to generate a Campbell diagram so that critical speeds of a nonlinear system can be assessed, providing a greater level of understanding of complex rotating components
