Railway Wheelset with Roller Bearing Axleboxes Cutaway (13 Bodies)
Complete 13-body railway rolling stock wheelset assembly with quarter-section cutaway through the right axlebox housing, inspection cover, double-row cylindrical roller bearing, and monobloc rail wheel.
Railway wheelsets carry static axle loads of 23.5–25 tonnes while transmitting traction, braking, and lateral flange guidance forces through the wheel-rail interface. This 13-body cutaway assembly reveals the internal fit of the monobloc wheel hub on the axle wheel seat, the labyrinth seal on the dust guard seat, and the double-row cylindrical roller bearings inside the axlebox housing.
1. Geometry & FEA Mesh
- •13 independent solid bodies: railway axle shaft, left & right monobloc wheels, left & right axlebox housings, left & right double-row roller bearings, left & right labyrinth seals, left & right end locking plates, and left & right inspection covers.
- •Zero CAD Collisions Gate verified: 0.000 mm³ overlap across all 13 bodies.
2. Loads & Boundary Conditions
- •Exact cylindrical clearances across wheel bores, labyrinth rings, bearing rings, and axlebox housings.
3. Simulation Results & Findings
- ✓13 railway wheelset and axlebox bodies load interactively in the browser with per-part material colors.
Demonstrates full multi-body rail rolling-stock assembly authoring and inspection in WebCAE.
