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
