Gearbox meshing-stiffness simulator

Explore a browser-based research prototype for spur-gear meshing stiffness, tooth faults and downloadable stiffness profiles over one 2π pinion revolution.

Browser research prototype

Gearbox workbench

Set the spur-gear geometry and material, optionally add a representative tooth fault, then inspect the profile over one complete pinion revolution. Angles are reported in radians and stiffness in N/m.

01 / Setup

Model inputs

Adjust the gear pair and tooth condition. Plot 1 previews the current geometry, Generate calculates only the current fault in Plot 2, and Add configured fault saves it into Plot 3.

Saved faults for Plot 3

Configure one tooth, then add it to the graph. Each tooth can have one fault. Remove a fault at any time.

    This interactive prototype is the first public step toward the RAMMS gearbox simulation work. Select the main spur-gear properties, optionally introduce a representative tooth fault, inspect the damage sketch and generate a meshing-stiffness profile over one pinion revolution. The downloadable CSV is intended for exploratory research and model development, not design certification.

    The implementation follows the parameter conventions and fault families in the accompanying Gearbox-Simulator repository. Once a profile is generated, the second stage can feed it directly into the supplied coupled gearbox dynamics models.
