Austin Passini 11/12/2014 Capstone Introduction Building a car is a complex process to say the least. There are extensive amounts of planning, designing, building, redesigning and communicating involved. One of the most difficult aspects though, is the planning. Every detail needs to be considered and every problem has to be foreseen before the actual product is built. This is especially true in the suspension and steering components; if something goes wrong with either of these systems then the car can veer out of control and crash. To minimize the change of an event like this happening, things like camber, caster and toe need to be taken into account. These factors have to do with the orientation of the wheel relative to the body, ground …show more content…
For one, the suspension is usually much stiffer than other set ups. This means that when the car is going around a corner the suspension will hold up more of the car. The weight of the car is also kept inbound of the wheels because the force is moving in a horizontal direction as opposed to a vertical direction. This is important when cornering because any unsprung weight (weight that the force is applied to the wheels or the tires) causes unnecessary stress on the frame of the vehicle as well as worsened handling and a lower efficiency. There are some down-sides though, at speeds above 50 miles per hour the upward force becomes too great for the pivot point to handle efficiently, and therefore the pivot point gets hung up and creates a lot of stress on the frame of the vehicle and does not actually dampen the force that is being enacted on the suspension system. It is also relatively …show more content…
Without a reliable and durable steering system the car could veer out of control endangering the driver, passengers and anyone around the vehicle. This means that the steering system has to be virtually perfect. There are two main types of steering systems the basic set up and then there is rack and pinion. The basic set up for steering a car involves a steering wheel, connecting rods, a gear box and the steering knuckle. This system takes the rotation of the steering wheel (and thus the steering rod) and via the gear box transforms the direction of the rotation 90 degrees so that when a rod is attached to the gear box the rotational motion is changed into a back and forth motion. This rod coming from the gear box is attached to the steering knuckle (on the wheel closest to the driver e.g.. the left wheel on a left hand drive car). This motion causes the hub of the wheel to rotate around the vertical axis of the king pin. There is another universal joint on the hub in which a tie rod runs the entire width of the vehicle connecting the two hubs. This allows the two hubs to rotate in exactly the same amounts at exactly the same time so that the wheels will always be traveling in the same

Tires are the most important part of race or any car for that mater. (Physics of Racing) After all they are the only thing that is contact with the ground! Tires work by having a high coefficient of friction. Some slicks have a friction coefficient grater then 1! (Physics of Racing) Typical normal street tires have coefficient of about .5 to .6 . In physics we learned that friction was equal to mew times the normal force. Since race cars are typical much lighter then normal cars, they use tricks to increase the downward force on the tires. Some drag tires run really low pressure, other drag cars tune the car to lift the front wheels to put all the weight on the rear tires. Indy cars use a wing to generate down force, and ventures to suck the car to the ground. (How to Make Your Car Handle)
Torque is what makes the wheels on the bike go round. Great research has been but into the sport in order to figure out how to increase the torque applied by the rider to the rear wheel, wile decreasing the torque required to make the wheel turn. Torque is produced the rider using a device called a crank.
There are many different types of suspension systems that are used in cars today, and some that were discontinued due to their uselessness. One example of an older suspension system is called the swing axle suspension. This is a very old type, used in many sports cars in the 50’s, but had disappeared for about 2 decades. This was due to the weakness of the system. The handling was awful, as the camber angle can be noticeably changed by a simple bouncing motion, and the change of the static weight and body roll as the car took a corner. The only advantage to this type of system was that it could provide independent shock absorption. (Wan)
Suspension and alignment are two of the most important part of our cars today. We rely on our cars to have good suspension system because our cars go through many different road conditions that can affect the way the car is driven. The alignment helps the cars maintain a correct suspension balance the cars need to be when functioning. There are many type of suspension and alignments type in our modern cars today. Without a good suspension and alignment system our modern cars could face many problems just getting around on the road. The suspension stabilizes the vehicle movement during acceleration, turning, and braking. The suspension helps eliminates the roughness of the road when driving. The suspension systems is made to maintain the vehicles correct ride high, support weight of the vehicle, maintain proper wheel alignment, keep the tires in contact with the road, control the vehicle direction of travel, and reduce the effects of shock forces.
The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in reasonable control.
Good stability and handling is achieved with a combination of suspension, steering, acceleration, brakes and weight distribution.
One of the very first things a buyer should consider when looking for a car is what kind of car he/she wants. Many different factors can affect the car buying process. For one, the buyer must consider how big of a vehicle he/she wants and safety features like airbags, seatbelts, and working brakes. Itemizing a list of accessories can also help narrow down what kind of car to buy. While some people might prefer a Sedan with a large back seat and seat warmers, others may prefer an extreme luxury car with full stereo systems and miniature televisions. Every person has different tastes in accessories; luckily, there is a vehicle that can fit almost every personality. Most new models have the latest technology installed, although some of the “newer” used cars have the option of adding in those accessories. Once the...

Cars general work with the engine turning over from the driver using their key which makes the four piston strokes start. Once that happens, it starts moving getting hot and while that is happening, it moves the transmission belt which moves the alternator, and the alternator starts generating power through kinetic energy which in turns keeps the battery powered so you don’t lose power while driving. After the engine does that then power is supplied to the various computers in the car which gets it started moving. The steering wheel is attached to a steering column and the several other parts of the steering linkage so steering is possible. The brakes have two different types on the front there can usually be disc rotors which work by the rotor being mounted on the rotor hub and held in place with the mounting bracket on the mounting bracket are brake pads which squeeze the rotor which cause the car slow down or stop. The brakes on the rear are drum brakes which are similar to disc brakes, but they have brake shoes which expand to stop or slow down the car. This is not always true though some cars just have disc brakes and some older cars have drum brakes the reason for this is because disc is more reliable than drum brakes. Of course after all that you would remove the key and it would then stop the engine and the belt from turning and then the majority of the electrical stuff turns off except for the battery.
The research provides a thorough overview of design and analysis of chassis and suspension system assembly of heavy vehicles. The chassis is a steel frame, supported on the springs attached to the axels that holds the body of a automotive vehicle. Suspesion is a system of springs, shock absorbers ,that connects the wheels to the vehicle that allows the relatives motion between them. Suspension system provides a dual purpose of vehicle road holding and handling for good activie safety. The fem analysis has been carried out with different alternatives.The result illuminate the new creative ways for optimum frame design.which makes more sustainable and structural concern.The chassis and suspension system is assembly is modelled
