RecurDyn RFlex - modal reduction
RecurDyn RFlex (Reduced Flex) gives you fast simulations with flexible bodies in your multibody dynamics system. RecurDyn RFlex represents flexible bodies using modal information that is output from Finite Element Analysis FEA software. RecurDyn RFlex also includes options to export body loads to FEA and to export modal participation factors. The RecurDyn RFlex technology is based on the modal reduction theorie of Craig Bampton.
Efficiently include flexible components within your RecurDyn full-system model.
Investigate effects due to the flexibility in the system, including enhanced vibration analysis.
Calculate more accurate loads in systems with path-dependent structures, for use in fracture or fatigue calculations.
Extracts modal results (FEA linear dynamics) from various FEA software:
- Siemens NX Nastran
- Importing the modal results of eigenvalue (linear dynamics) analysis from various FEA software NX Nastran, ANSYS, ANSYS DesignSpace, Ideas, and MSC Nastran.
- Converting rigid bodies into FE models while maintaining the condition of constraints (Flexible Body Swap function).
- Marking stress, strain, contour, creating the elastic quantity automatically.
- Exporting data in the FEMFAT format for use in the fatigue analysis.
- Supports constraint (static correction) modes, due to unit displacement of boundary nodes, created by FEA software
Supports attachment (dynamic correction) modes Reduces errors identified during the simulation,
Dynamic mode created by RecurDyn
RecurDyn RFlex performs the elastic mechanical analysis considering the linear elastic effect, after bringing FE models from the FEA software.
