3. Automated and Intelligent Load Transfer for FEA

To generate accurate loads, physical tests, empirical values, or just outright guesses are often used. But this is expensive, time consuming, and often inaccurate. Transient FEA can calculate the loads. But difficulty of use, slow calculation, and poor convergence are barriers to using transient FEA.

MBD for ANSYS can generate accurate loads and provides automated and intelligent load transfer process.

4. Scalability to various Multi-Body Dynamics applications

  • MBD for ANSYS can be used to understand the dynamic behavior of basic mechanical assemblies and generate loads for structural analysis.
  • In addition, there are many applications of Multi-Body Dynamics such as complex assemblies with vibration problems; mechatronic systems that couple mechanical assemblies, sensors and controllers; and complex multi-body systems with chains, belts, bearings, gears and track assemblies.
  • Some systems require the co-simulation of mechanical assemblies and fluids using particle dynamics. MBD for ANSYS lets you export your model to the RecurDyn standalone, high-end MBD software, which is able to simulate such complex multibody systems.
