Overview
As the world transitions from fossil fuels to green energy, manufacturers are leaning towards more fuel economic and zero emission transportation vehicles. The objective of this team project was to design a two-wheeled electric motorcycle (EleCycle) for urban environments, focusing on chassis, FEA, fatigue, and transmission design.
Problem Statement
- Design a lightweight, robust electric motorcycle chassis for two passengers
- Ensure safety, reliability, and manufacturability
- Optimize for urban driving conditions and daily use
Solution
- Concept sketches for different chassis designs (Dually, High Rise, Streamliner)
- FEA and fatigue analysis at each design stage
- Transmission system design and decision matrix for selection
Technical Implementation
Chassis Design & Analysis
- Preliminary chassis design and FEA (stress, strain, displacement)
- Iterative design improvements based on analysis
- Final Streamliner chassis design and assembly
Transmission System
- Concept sketches: worm gear reducer & V-belt, spur gear train & chain
- Decision matrix for selection (safety, cost, longevity, reliability, maintenance, size)
- CAD models for transmission system (sketch, gear train, chain drive, shaft)
