Automobile chassis,types of automobile
There are different types of automobile bodies depending on usage and vehicle type. Bodies are divided into passenger and commercial bodies. Vehicle bodies must meet certain requirements like being light, having sufficient space, withstanding vibrations and providing good visibility. The chassis, frame, and body are the main components of a vehicle. The chassis carries the load and withstands forces from braking, acceleration, and road conditions. Chassis frames can be conventional, integral, or semi-integral depending on their design and construction.

Air bearing
An air bearing is a non-contact system that uses a film of pressurized gas, usually air, to separate two surfaces moving relative to each other. It has less friction than other bearing types like rolling or plain bearings since there is no contact between surfaces. Air bearings also don't require lubrication and have long lifespans. There are two main types: aerostatic bearings which provide high lift and aerodynamic bearings which provide enough lift to float loads of up to 100 tons. Air bearings work by inflating to form a seal and allowing compressed air to escape and float the load above the surface. They have applications in lifting heavy weights and hovercraft transportation.

The Effect of Orientation of Vortex Generators on Aerodynamic Drag Reduction ...
One of the main reasons for the aerodynamic drag in automotive vehicles is the flow separation
near the vehicle’s rear end. To delay this flow separation, vortex generators are used in recent vehicles. The
vortex generators are commonly used in aircrafts to prevent flow separation. Even though vortex generators
themselves create drag, but they also reduce drag by delaying flow separation at downstream. The overall effect
of vortex generators is more beneficial and proved by experimentation. The effect depends on the shape,size and
orientation of vortex generators. Hence optimized shape with proper orientation is essential for getting better
results.This paper presents the effect of vortex generators at different orientation to the flow field and the
mechanism by which these effects takes place.

Car’s Aerodynamic Characteristics at High Speed Influenced by Rear Spoiler
This study analyzed how different rear spoiler designs influence the aerodynamic characteristics of a car at high speeds. Nine rear spoiler cases were modeled varying the cross-sectional shape, chord length, and horizontal angle. Computational fluid dynamics simulations were run to calculate the aerodynamic lift coefficient for each case. An orthogonal experiment design was used to analyze which factors had the most significant influence on lift. The results showed that cross-sectional shape, chord length, and horizontal angle all had a minor significance. The best combination found was a flat cross-section, 150mm chord length, and 15 degree horizontal angle, which reduced lift the most.
Design of Rear wing for high performance cars and Simulation using Computatio...
The performance of a sports car is not only limited to its engine power but also to aerodynamic properties of the car. By decreasing the drag force it is possible to reduce the engine power required to achieve same top speed thus decreasing the fuel requirement. The stability of a sports car is considerably important at high speed. The provision of a rear wing increases the downforce thus reducing the rear axle lift and provides increased traction. In this study an optimum rear wing is designed for the high performance car so as to decrease drag and increase downforce. The CAD designed baseline model with or without rear wing is being analyzed in computational fluid dynamics software. The lift and drag coefficient are calculated for all the design thus an optimum rear wing is designed for the considered baseline model.

Drag Reduction of Front Wing of an F1 Car using Adjoint Optimisation
The Project Poster summarizes the aims and objectives of the Final Year Dissertation. The project starts with a detailed study on the parameters that tend to affect the performance of front wings of an F1 car and goes through designing the front wings(3) with endplates and wheel, meshing it, solving/analysing the flow and finally optimising the selected geometry using Fluent Adjoint Solver for efficient performance.
Adjoint optimisation technique is used to achieve optimal performance from the front wings. It's the most successful shape optimisation method as it's independent of the number of design variables exponentially reducing computational time and cost. The emphasis has been put on optimising the shape of the front wings using the Adjoint method as it’s the most efficient and computationally inexpensive method for design optimisation. The approach towards shape optimisation is downforce constrained drag minimization as it would result in keeping a constraint on downforce and reducing the drag at the same time, thus producing optima for a given downforce/drag value.

Increasing Downforce In High-Speed Vehicles Using Wheel Rotation
The document discusses increasing downforce in high-speed vehicles through wheel rotation. Downforce increases tire grip and allows vehicles to corner faster by creating a downward aerodynamic force. Traditionally, downforce was increased through spoilers and wings, but this also increased drag. The authors propose adding propeller-like structures to the wheels to actively increase downforce without increasing drag, by sucking air beneath the vehicle. This method was inspired by fan cars from the 1970s but would use passive devices on the wheels instead of active fans.

Aerodynamics pertaining to vehicles focuses on improving the drive-ability of the vehicle while also reducing
losses due to air drag. This paper focuses on maximizing the cornering performance of the formula student race car with
slight modifications to the airflow around the vehicle and meagre addition of weight. The undertray produces downloads
by altering the velocity of air flowing underneath it. The sidepods act to reduce flow velocity above the undertray, thus
increasing the pressure above it. This leads to an increased pressure difference over the surface of the undertray which
translates to increase in downforce. The car is able to have a 10% decrease in lap times on a 500m racetrack.
