FFlex Static 글 편집

Through more than two years of intensive research and development, the N-R Static Solver's performance has been significantly improved.

This allows the stable and accurate Static Equilibrium State calculations of both Rigid and RFlex bodies.

Based on the N-R Static Solvers, FFlex Static can perform static analysis of nonlinear MFBD models that include FFlex bodies.

The static equilibrium state of an MFBD model can be calculated quickly and accurately​

Features

  • Structural analysis of flexible bodies can confirm deformation and stress in a static state.
  • Supports static analysis of an MFBD model considering not only self contact of FFlex body but also contact with other bodies.
  • When a deformed shape of a flexible body is required, it can be obtained by using static analysis and extracting the results.


Benefits

  • By calculating the initial equilibrium state of a model such as vehicle or excavator in advance, the simulation speed and accuracy can be improved.
  • Total simulation time can be reduced by tuning a model through static analysis before dynamic analysis.
  • When the effect of inertia is small, the behavior of the model can be quickly observed using quasi-static analysis.
  • It is possible to investigate the system’s range of motion or the interference between bodies through static analysis.

Note

  • For models containing only rigid bodies and RFlex bodies, static analysis is possible without additional licenses.​
  • For models with FFlex bodies, an additional license (FFlex Static) is required for static analysis.​
    • In RecurDyn 2023, FFlex Static is provided as a beta function (Rigid/RFlex static is an official feature).​
