SAE EffiCycle 2019

Situation: The EffiCycle 2019 competition required the design and development of an innovative and sustainable tadpole-type three-wheeled hybrid vehicle. The project emphasized improving performance metrics like speed, acceleration, and efficiency while adhering to environmental and safety standards.

Task: Collaborated with a team of 13 students to design a vehicle that met competition requirements such as reduced noise levels, better maneuverability (reduced turning radius), and enhanced stability (lower center of mass). Your specific role involved focusing on the vehicle's design, performance optimization, and usability enhancements.

Action:

1. Vehicle Design:

   • Designed the three-wheel structure using CAD tools to ensure better weight distribution and stability.

   • Integrated independent suspension systems to enhance ride quality and reduce vibrations.

2. Performance Enhancements:

   • Reduced vehicle weight by 5 kg through material optimization and design streamlining.

   • Improved acceleration from 0.9 m/s² to 1.15 m/s² and maximum speed from 9 m/s to 13 m/s in hybrid mode, leveraging aerodynamics and powertrain modifications.

3. Accessory Integration:

   • Enhanced usability by incorporating features like headlights, taillights, and solar panels for energy-efficient night-time travel.

   • Designed a solar-powered system to operate vehicle components, promoting sustainability.

4. Collaboration and Testing:

   • Coordinated with team members to conduct rigorous testing under different conditions, iterating the design for optimal results.

Result:

• Secured 13th position nationwide, demonstrating innovation and practicality in design.

• Enhanced vehicle performance metrics, with notable improvements in speed, acceleration, and energy efficiency.

• Developed a hybrid vehicle capable of sustainable night-time travel using solar power.

Growth:

• Gained expertise in CAD design tools, aerodynamics, and vehicle dynamics.

• Improved project management and teamwork skills, effectively coordinating with a diverse team.

• Deepened understanding of integrating sustainable energy solutions in vehicle design.

• Strengthened technical problem-solving and innovation skills, applying them to achieve tangible results.
