Rolling Element Bearing Software

Capabilities

RAPPID™ rolling element bearing analysis software utilizes a quasi-static solution and offers the following capabilities:

  • Simplex and duplex ball
  • Cylindrical roller
  • Tapered roller
  • Spherical roller

Features

RAPPID™ rolling element bearing analysis software has a wide array of features are available to enable physically realistic modeling of rolling element bearings, including:

  • Full non-linear treatment of Hertzian contact between rolling elements and races
  • Deadband model predicts asymmetric direct stiffness rotordynamic coefficients

Analysis Results

RAPPID™ rolling element bearing analysis software yields results needed for a comprehensive assessment of bearing rotordynamic performance, including:

  • Direct stiffness coefficients, axial endplay, and approximate 5 DOF stiffness matrix
  • Calculates individual element loading, contact angle, and stress
  • Reports defect frequencies
