SUPRA

SUPRA is organized annually by SAEINDIA with the support of Maruti Suzuki. The event provides a platform for students to apply their engineering skills to design and construct a Formula category vehicle as per defined performance and safety specifications. Competition comprises of a series of Static and Dynamic events spread over five days, concluding with a final endurance run.

My Roles:

Design and manufacturing of steering system

We took a unique approach to modular design to reduce the weight and improve repairability. While the casing and steering rod were made from Al-6061 t6, we chose 20MnCr5 for the gear mechanism. This combination allowed to lower weight over conventional OEM steering assembly by 50%

However, we underestimated aluminum's wear rate. The friction between the casing and rod caused by the lateral forces caused wear and developed play. Later, we used surface hardening to reduce this wear.

Finite Element Analysis (FEA)

After the initial design is complete, we would submit it to the FEA team along with the data for expected loads in static and dynamic conditions. Then, we would verify the outcome with our theoretical calculations. The goal is to minimize material to reduce weight while maintaining a Factor of Safety of 1.5.

We have also used this analysis to compare effects of different materials, geometries and compositions.

Business case study

Assume that we are a startup and pitch to the investors, convincing them to invest. In this presentation we demonstrated Unique selling points, manufacturing strategy, target market, promotional strategies and financial breakdown of our budget. In 2018 season, we were ranked 8th among 180 participants.
