Analysis of Rail Vehicle Suspension Spring with Special Emphasis on Curving, Tracking and Tractive Efforts

Failure in wheels mainly occurs when the train travels on a curved track. When a train runs on a curve maximum load on one wheel. Three types of forces are applied on the wheel while in contact with the rail. Three-dimensional finite element model of the wheel rail interaction is used to investigate the effect of applied loading forces on the wheels. The Interaction between left and right wheel is considered. The wheels are analyzed for the effect of forces on wheels such as Vertical force, Centrifugal force and also Lateral force. This paper also discusses the comparison of safe speed and radius of curvature. The model has been created in Catia software and the finite element analysis has been done in software code and ANSYS. The proposed simulation accurately shows the real geometry and the wheel rail interface. The numerical results show that the speed and radius of curvature are inversely proportional.

“…Friction brakes are the most popular braking mechanism in commercial or special-purpose vehicles [17][18][19][20]. They're often rotating devices with a spinning wear surface, such as a disc or drum, and a stationary pad or shoe [21][22][23].…”

Many difficulties surround the heating characteristics of brakes when it comes to their creation, including contact region features, material choice, development of hot spots, associated physical geometry, and deformations, as brakes are subjected to continuous operation. Therefore, it is must for all vehicles to have proper brake system. In this report there is the modification of the disc and that results in the design are used to carry out analysis on it. The analysis of standard disc brake model and new design using in Ansys is done the Thermal analysis and Modal analysis also calculate the deflection and Heat flux, Temperature of disc brake model. Understanding the different forces (action and friction) which are acting on the disc brake, as well as how the disc brake operates more efficiently, will assist to reduce the number of accidents that occur each day. The primary goal of this research is to examine the brake disc's thermo-mechanical behavior during braking. The disc material is changed to carbon-ceramic, and the results of the FEA of the new design disc are used. This study presents the findings and the disc's future prospects.
