The 6-Stage Development Lifecycle
A closed-loop engineering cadence transitioning from pure CAD parametric sweeps to calibrated physical digital-twins.
Conceptual Architecture
P5-P95 CAD boundary definition, space envelope constraints, clearance corridors for high-speed bi-level and single-deck railcar structures.
Multi-Body Kinematic Linkage
Synthesis of smooth zero-pinch 5-bar linkage systems. Optimization of pivot trajectory, micro-actuator strokes, and anti-rattle friction dampening.
Non-Linear Crash Dynamic FEA
Dynamic impact simulation calculating 18G longitudinal deceleration pulses and passenger head injury criteria (HIC < 500) per EN 15227 and GM/RT2100.
Rapid Functional Prototyping
Bespoke CNC aluminum machining and SLS 3D printed functional components. Optical CMM coordinate measuring with sub-micron 0.002 mm accuracy.
