About Product
Magnetically levitated bullet trains are the most interesting development of the new millennium, recording travel at unheard of speed levels. The train levitates above the tracks using electromagnets to create a nearly frictionless ride, without making contact with the ground. Moving more smoothly and quietly than wheeled mass transit systems, the power needed for levitation is mostly to overcome aerodynamic drag.
A confluence of superconductivity and magnetic technologies has produced this spectacular event. Superconducting magnets do not dissipate energy to maintain the magnetic field. A superconductor levitated above a permanent magnet remains in stable equilibrium. Resistance to flow of electric current in the conductor vanishes, so the magnetically levitated coaches operate without external energy. At the same time, however, initial cost of development and installation is prohibitive.
Regular wheel-on-rail form of transport powered diesel engine locomotives is the answer. Electric generators convert the mechanical power into electricity. Asynchronous induction motors develop tractive power for wheeled high-speed trains to provide a comfortable ride. Distributed power over multiple axles of the locomotive lets the train smoothly accelerate and decelerate at a fast pace. One or more locomotives can travel at speeds of 150 km/h, while pulling a load of up to 1,000 tons.
This book provides tools for design and operation of a massive locomotive pulling a heavily loaded train through mountainous regions. Extracting maximum power, emit acceptable levels of exhaust pollutants, accelerate smoothly and safely come to stop are of significance. Passenger coaches must not pitch and roll when subjected to strong cross winds, and while negotiating sharp curves.
This book provides tools to understand and evaluate the dynamics of designing reliable high-speed train systems that will serve the community over a lifetime. Sophisticated design and development methods provide automatic protection from a host of unforeseen circumstances. New research discoveries aid in maximizing safety, speed and efficiency while enhancing the accrued benefits from the investment.
Safeguards from dynamic operating conditions are required to avoid failures from: Train derailment due to deformed wheel and deficiencies in track pathway, Establish dynamic loads from interaction between wheel, rail and track ballast Design compliant mount between vehicle body and bogie wheel assembly Rolling contact stress and thermal fatigue in wheel from abrupt brake application.
