The Mizzou Hydrogen Car Team focuses its engineering efforts on the design and construction of the Tigergen III, a vehicle specifically developed for the Urban Concept hydrogen fuel cell category. The team, composed of students from the University of Missouri in Columbia, Missouri, prioritizes efficiency and structural integrity to compete in events such as the Shell Eco-Marathon. The vehicle's design philosophy centers on minimizing weight while maximizing aerodynamic performance and safety, which are critical factors in achieving high energy efficiency metrics.Structural Composition and Materials
The Tigergen III utilizes a partial-monocoque composite body structure. This engineering choice allows for a lightweight yet rigid chassis that supports the internal components while contributing to the vehicle's overall aerodynamic profile. The primary materials used in the construction include carbon fiber and Nomex. Carbon fiber provides high tensile strength and stiffness, which is essential for maintaining the vehicle's shape under aerodynamic loads and during dynamic maneuvers on the track. Nomex, a meta-aramid synthetic fiber, is incorporated for its thermal resistance and lightweight properties. This combination of materials ensures that the vehicle remains durable during competition while keeping the total mass low, directly impacting the energy consumption per mile.
Safety Features and Engineering Details
Safety is a paramount concern in the design of the hydrogen fuel cell vehicle. The Tigergen III is equipped with a five-point harness system to secure the driver. This configuration provides superior restraint compared to standard three-point belts, distributing crash forces across the shoulders, hips, and between the legs, which is crucial in a low-profile urban concept vehicle. Additionally, the vehicle features a fire-resistant bulkhead. This structural element serves to compartmentalize critical components, potentially isolating the hydrogen storage system or the fuel cell stack from the driver's cabin in the event of a thermal event or mechanical failure. The integration of these safety features reflects the team's attention to detail and adherence to competition regulations, ensuring that the vehicle is not only efficient but also reliable under competitive conditions.
Performance Context
The engineering decisions made for the Tigergen III were validated during the 2013 Shell Eco-Marathon. This performance metric demonstrates the effectiveness of the partial-monocoque composite body and the strategic use of carbon fiber and Nomex in reducing energy loss. The team also received an off-track award for "Best Team Spirit," highlighting the collaborative engineering effort behind the vehicle's development. The successful integration of hydrogen fuel cell technology with advanced composite materials underscores the team's capability to produce competitive, high-efficiency vehicles for urban mobility concepts.
What are the objectives of the Shell Eco-Marathon?
The Shell Eco-Marathon is a global engineering competition that challenges student teams to design and build vehicles that maximize fuel efficiency rather than raw speed. The core objective is to demonstrate how emerging energy technologies can reduce global fuel consumption. Participants must balance aerodynamics, weight reduction, and powertrain optimization to achieve the highest possible distance per unit of energy. This focus on efficiency mirrors real-world energy infrastructure goals, where minimizing loss is critical for sustainability.
Competition Format and Efficiency Metrics
The competition measures performance in miles per kilowthour (mi/kWh) for electric and hydrogen fuel cell vehicles. The formula for efficiency is straightforward: total distance traveled divided by total energy consumed. Teams aim to minimize energy waste through thermal management and regenerative braking. The Mizzou Hydrogen Car Team, for example, achieved 8.8 mi/kWh with their "Tigergen III" vehicle in 2013, placing third in the Urban Concept Hydrogen category. This metric allows for direct comparison between different fuel types and vehicle designs.
Urban Concept Category Constraints
The Urban Concept category imposes specific design constraints to simulate future city transportation. Vehicles must have four wheels, functional brake lights, and sufficient luggage space for a standard suitcase. These requirements force engineers to integrate practical features without sacrificing aerodynamic efficiency. The team must also ensure the vehicle can navigate a 6-mile circuit in Houston, Texas, which includes turns, straightaways, and a pit stop. The circuit tests both steady-state efficiency and transient performance. The Mizzou team also won an off-track award for "Best Team Spirit," highlighting the collaborative nature of the engineering process.
Engineering Challenges
Designing for the Urban Concept class requires balancing multiple competing factors. Aerodynamic drag increases with speed, so teams often use teardrop-shaped bodies to reduce air resistance. However, the luggage space requirement adds volume, which can increase drag if not integrated smoothly. Weight is another critical factor; every kilogram adds to the energy required for acceleration and climbing. The hydrogen fuel cell system must be compact enough to fit within the vehicle's footprint while providing sufficient power for the 6-mile circuit. The Mizzou team's success with "Tigergen III" demonstrates the effectiveness of integrating these constraints into a cohesive design.
