FSAE Wheel-side Motor Reducer Design
Period: In progress
Overview
Designed a single-stage planetary gear reducer for the USTB Dingchi E-New ERA 2027 rear-wheel-drive dual in-wheel motor racing car (DTI F-MOT-B motors). Performed parametric sweep optimization across 5 gear ratios (i=8.0 to i=11.33), including ISO 6336 strength verification, μ-sweep acceleration analysis, bearing selection, and mass estimation. All calculations verified with Python scripts.
Highlights
- 5 gear ratio configurations (i=8.0-11.33) with parametric μ-sweep optimization
- ISO 6336 Method B strength verification with 99.9% reliability target
- Custom Python scripts for acceleration simulation and ratio comparison
- Bearing selection & mass estimation (lightest ~1.4 kg)
