A browser-based engineering suite for analyzing prop-shaft geometry, phase, and kinematics across vehicle operating conditions.

Landing page captured for the 2026-08-28 issue.

Field notes

The application organizes driveline analysis around vehicle inputs, shaft configurations, and editable three-dimensional geometry. Its visible workflow includes tire and axle-ratio selection, manual or calculated shaft RPM, requirement thresholds, baseline-versus-modified comparisons, and multiple shaft layouts. A displayed example runs at 3,853.1 rpm, while the coordinate system defines forward, lateral, and upward axes for entering transmission, joint, and axle locations. The interface also exposes phase-sweep, response-map, optimization, and report sections.
