The aerodynamic braking is a clean and non-adhesion braking system, and can be used to provide extra braking force for high-speed trains. Unlike the wheel disc brake and sliding frictional shoe brake, the aerodynamic brake is a system which does not make use of mechanical friction as braking force, and designed to generate braking force by increasing aerodynamic drag force with a panel unfolded on the top of the car. The qualities of this system are high reliability and reduced maintenance cost, because there is no wearing of components and heating due to friction. As a new high-speed train braking mode which involves no pollution and is good to the environment, there is great possibility that the aerodynamic brake system becomes an important
1. Four DOF suspension model Identified design parameters that govern the dynamic behavior of a vehicle’s body considered for study are tabulated in table 1. TABLE I PARAMETERS USED IN SYSTEM MODELING Nomenclature Mass of vehicle’s body, kg Total Length of the body, m Length of the body front and rear end from centre of gravity,
Vehicle ride comfort is one of the most important performances of vehicle; the research of automotive ride comfort is getting more and more important. In this paper is to design and develop a system that is “Automatic ground clearance adjustment system” to overcome this problem by adjusting the ground clearance over this particular time period. Automatic ground clearance adjustment system mainly consists of six major parts such as Chassis, D.C motor, Embedded Development board with Radio Frequency Modules (Encoder & Decoder) and micro controller, IR sensors, alarms, indicators and batteries. The average time required by the system to vary the ground clearance of the vehicle is two seconds. The cost of implementing this system is also low.
Experiment 1 Two types of shapes – a sphere and a gear – were used in Experiment 1 (see Videos 1-30). Individual shapes subtended approximately 6.5° of the visual angle vertically and horizontally and consisted of 500 dots distributed randomly over their surface. For the ambiguously rotating shapes, the dot diameter was equal to 0.23° (see Figure 1A-C). When we biased the direction of rotation via perspective cues, the dot diameter was systematically varied between 0.10°
When they extricated car from the hood, I had never seen an entire crowd, so excited about the speed of a car in my entire life. The primary characteristic of a car should be the fun factor. What made it so much more interesting than the car is simple: a great fun factor concept. When there is a unique fun factor, the car is ultimately better, and these fun factor concepts have similar qualities. The biggest factor of a good sports car would be the speed of the car.
Steering arrangement WORKING AND DESCRIPTION: In four-wheel steering systems, the rear wheels are steered by a computer and actuators. The rear wheels generally cannot turn as far as the front wheels. Some systems allow the rear wheels to be steered in the opposite direction as the front
Motion is the change in position over time against a reference point, and is the procedure of an object changing place or position. Sir Isaac Newton, a famous mathematician and scientist, had created three laws based on motion. The first law was based on inertia, the tendency of an object to resist any change in motion, which states, “Objects at rest, stay at rest, unless acted upon by a force,” and, “Objects in motion, stay in motion, unless acted upon by a force.” This law explains that if an object were to travel at a constant speed in the same direction, it would continue to do this until it is pulled or pushed by something. If we think about a gravity-free zone, such as space, we could picture throwing a rock out into outer space. And this marble would continue to go at the same speed in the same direction unless there is a force, a push or pull, acting upon by it, making it either slow down, speed up, or just change it’s direction.
It is also powered by Twin clutches which assists in quicker shifts and improved driving experience. It also helps to de-clutch front wheels automatically when not required and thus enables rear-wheel drive.. It also helps to achieve torque vectoring between wheels and axles by means of electronic controls. The complete system is water-cooled which assists in improved performance levels. Rear axle gets a differential lock which assists in enhanced road conduct Chassis and suspension is based on aluminum and steering is amplified with electro-mechanical assist.
Each gain in height corresponds to the loss of speed as kinetic energy is transformed into potential energy and vice versa. This model demonstrate the transformation of mechanical energy from the form of potential to the form of kinetic and vice versa. Mechanical energy refers to the total of potential energy and kinetic energy in a system: KEi + PEi = KEf + PEf. The principle of conservation of mechanical energy states that total mechanical energy, which is the addition of potential energy and kinetic energy, remains constant as long as the only forces acting are conservative forces. “A conservative force is defined as a force with the property that the work done in moving an object between two points is independent of the taken path.” ( Robert A. Pelcovits, 2002) Example of conservative forces in this project is gravitational potential energy.
