Cranktrain VARIETY OF PRACTICAL ENGINEERING ANALYSES

In addition to crankshaft definition with basic dimensions and material properties, GT-SUITE offers a streamlined process for importing solid models to extract key geometry, mass and moments of inertia.  The crankshaft can easily be switched between rigid, torsional and bending models for balance, vibration and stress evaluation respectively.

The cranktrain application supports a library of bearing models of various levels of fidelity from basic mobility to formal EHD solutions.

Additionally, skirt and ring models are available for preliminary friction prediction and evaluation at the concept phase.

Cranktrain APPLICATION HIGHLIGHTS
