'Team Nitte Racing' has secured 11th place in India and 1st place in state at Mega ATV Championship - NMAMIT

Team Nitte Racing' has secured 11th place in India and 1st place in state in a All terrain Vehicle event “Mega ATV Championship” which was organized by Autosports India in collaboration with fmsci and Kalinga University which was held at Bhubaneswar between 4th - 7th of March,2016.







Report in detail: 
Team Nitte Racing (TNR) had participated in a mega event which is named as “Mega ATV Championship” which was organized by Autosports India in collaboration with fmsci and Kalinga University, bags 11th position in India and 1st in the state. TNR, with the tagline “Rise from the ashes” is based on its theme on a phoenix which resembles that although we might face difficulties on the path we still never give up, hence we go. The event was held in Bhubaneswar between 4th - 7th of March,2016, around 70 teams participated from all across the country. The event started with the technical inspection wherein every vehicle was checked thoroughly to meet the rules and safety concerns, where TNR cleared it with appreciation. Then there was the brake test which was cleared by the team in its first attempt. Team Nitte Racing secured 8th position in the flat dirt race, 2nd in land slide simulation, and completed 6 Laps successfully without breakdown in the final endurance race, thus securing 11th position in India and 1st in the state.

Background Information: During the manufacturing process of the vehicle. Team Nitte Racing (TNR) 2016 consists of active 28 members putting their minds together on creating a commendable performing ALL TERRAIN VEHICLE which saves lives. The basic idea of the vehicle was jotted down by members of various subsystems keeping the rulebook into account. After various brain storming sessions and iterations, the Team cameup with the design of a car which was completely new to their experience.

The design of the buggy started with the motive of making a chassis which weighs less, occupies less space, ergonomically good and which is safe for the driver. Each and every part that had to be installed was discussed keeping the safety of the driver in mind and also whether it would meet the requirements of other subsystems.

For transmission, since the team had decided to go for a CVT it posed a challenge of choosing a suitable drive train and also its placement without affecting the rear suspension geometry. The subsystem members in this process designed and machined their own aluminum damper, gear boxcoupler, coupler shaft, cvtbolt and double CV joint shaft. This was a huge learning experience for the team.

The suspension started with choosing which type of configuration will suit our requirements and whether those components will be easy to design and manufacture and then it was decided on going with double wishbone in the front and a pure trailing arm in the rear. The design of the front suspension geometry and arms were relatively simple since team members had a bit of experience in it, but the trailing arm posed a huge challenge for them. TNR decided and designed a trailing arm in which the knuckle would be simple but strong and the current design is what they could achieve the above requirements to the best.

When it comes to wheel assembly the knuckle and hubs are custom made keeping the specifications in mind. Initially they faced problem in integrating the custom made parts with the OEM which was sorted out by considering various ideas from members and experts. Braking system started with the selection of brake calipers in order to reduce the weight to the minimum and to integrate with the knuckle. Due to the problem faced with the OEM pedal ratios we designed our own brake pedal keeping the ratio 6:1 .

In order to cut cost a center point rack and pinion was designed and machined by the members of the subsystem. The steering arm and rack placement was decided on basis of getting the maximum response and we succeeded in getting an Ackerman % of 120.
