P-52 adaptors

  • 10 different adaptors were studied
  • Complex Geometry: 5 main components + approximately 20 auxiliary components, like bolts
  • Simulation to most critical loading operations (about 3 static studies)
  • Geometric Idealization: simplification of CAD geometry, for usage in numerical simulation, done in ANSYS DesignModeler
  • 5 Different material models, considering non-linear elastoplastic behavior. Large deflection effects are considered
  • About 15 non-linear contacts between main components, including friction and separation
  • About 20 linear bonded contacts, mostly for the bolt joints
  • Static evaluation is performed according to criteria defined by API 2RD.
  • A complex simulation, highly non-linear, executed directly in WorkBench
FATIGUE ANALYSIS INFORMATION
  • Same geometric model as the static studies
  • Contact non-linearities and large deflection are considered; material models are linear
  • A pair of multi-step simulations is used for each studied slot.
    Represents maximum and minimum operation angles.
    Each step is related to a specific loading class.
  • Results from ANSYS analysis are imported and processed in an external MathCAD routine.
    Two fatigue curves are solved (base material and welds)
    A results file is generated and imported back into ANSYS for damage plots.

ESSS NA is now evaluating the implementation of this fatigue calculation in ANSYS nCode DesignLife

- Fully-integrated with ANSYS WorkBench Accumulated damage calculation available

- Easier usage, without file operations between software

- Improved results, with hotspot identification and multiple fatigue curves definition
