Share results seamlessly in Simcenter 3D

  • Accurately predict complex engine behavior

  • Quickly create and maintain motion models using an integrated CAE environment

  • Integrate systems and controls to simulate mechatronic systems

  • Use add-on modules to simulate specific applications like tires, transmissions or hoses

  • Seamlessly share and use motion simulation results in Simcenter 3D as input for use in other types of CAE applications

​

​

The Simcenter 3D motion solution is part of a larger multidisciplinary simulation environment and is integrated with Simcenter 3D Engineering Desktop at the core for centralized pre/post processing for all Simcenter 3D solutions. This integrated environment helps you achieve faster CAE processes and streamline multidisciplinary simulations that integrate motion and other disciplines, such as finite element models for flexible body analysis, as well as connections to acoustics for gear noise analysis.

​

​

Designersand analysts often approach motion simulation from two different perspectives, where CAD designers start with CAD data and analysts often start with a blank slate. Simcenter 3D Motion solutions provide solutions that work with any user. Analysts can use Simcenter 3D Motion to manually create new engine models using simple primitive geometry for linkages. This helps you understand how a new assembly mechanism might work before applying any detailed geometry. Designers working with computer-aided design (CAD) assembly models during the detailed design stage can quickly convert these assemblies into a working motion model in seconds, converting the geometric bodies into mechanism links and the assembly constraints into corresponding motion joints. This can save designers critical modeling time so they can begin to understand how the geometry will affect the performance of their engine.

​

​

Simcenter 3D Motion solver is built on over 30 years of proven technology and uses the most advanced multibody numerical resolution techniques to provide fast, stable and robust simulation. Furthermore, it provides accurate results for reaction forces, displacement, velocities and accelerations for rigid and flexible bodies. The loads obtained in the simulation can also be applied in structural analyzes and durability, noise and vibration studies.

​

​Simcenter 3D can be integrated with leading control design tools and supports model switching and co-simulation methods to solve mechanical system equations simultaneously with controller or actuator system equations. This helps you understand how the controls will affect the engine's overall performance.

​

​

For certain types of structural, acoustic, vibration, and durability analyses, it is critical to understand the loading conditions for the part or assembly being analyzed. You can seamlessly transfer loading conditions calculated with Simcenter 3D Motion solutions into Simcenter 3D Engineering Desktop for use in other simulation applications. This will greatly improve productivity for you or your extended simulation team.
