Project Name : The Theory Of Tilting Train
Theme Name : Transport & Communication
Aim/Objective: To prepare a model to show how we can implement superfast trains in Indian Railways without replacing the tracks.
Scientific principle involved:
The Tilt Concept
A train and its passengers are subjected to centrifugal forces when the train passes horizontal bodies inwards in curves are often called tilting trains. Tilting trains can be divided in two by an actuator, usually hydraulic or electric. Tilt as such has normally not an impact on safety curves. Car body roll inwards reduces the centrifugal force felt by the passengers allowing the gravity of the car body. In a curve, under the influence of centrifugal force, the lower part of groups: the passively tilted trains, called naturally tilted trains in Japan, and the actively tilted of actively tilted train, as the centre of gravity does not essentially change its (lateral) position. reduce the lateral force perceived by the passenger safety due to the lateral shift of the centre of gravity of the car body. The active tilt relies on active technology, controlled by sensors and electronics and executed the basic concept of tilting trains isthe roll of the car bodies inwards the curve in order to the car body then swings out wards track cant, or when the track cant is insufficient, car body tilt. Trains capable of tilting the train to pass curves at enhanced speed with maintained ride comfort. Roll may be achieved by trains (active tilt is called forced tilt in certain publications).
Materials Used:
Microcontroller, Motor driver, Comparator, Capacitors, Resistors, Rx-tx module, Three bo motors, Almanac sheet, Thermocol sheets, Fevi quick glue, Pcb, Soldering kit
Working: The method for obtaining the tilt is that as soon as curve arises the sensors will detect it and send information to the digital display present in the engine coach. The drivers will respond to it by activating the hydraulic system which will tilt the train coach & hence skidding of train will be avoided. The trains need not to be decelerated on curves.
Since, at our level we are just giving the principle for this theory. We have prepared a prototype model which works on Rx-Tx module. We are using Tx module for tilting the train either side by pressing the two push buttons for left & right tilt.
Rx module receives the transmitted signal and responds to it accordingly using the micro-controller based circuitry.
Utility and Further Scope of the Project: Theory of the tilting train aims at providing superfast means of transportation to the passengers as well as increasing the comfort level of the passengers.
Thus, the theory of tilting trains has wide range of application in the transportation system as it aims at providing modernized, improved, technologically advanced, faster & better means of transportation.
Hence, the tilting train theory is a very useful project for the Indian Railways to work upon in the upcoming future.
