“…There are various parameters which affect the design and maintenance of horizontal curves are radius (R), cant/superelevation (C), equilibrium speed (Veq), cant deficiency (Cd), cant excess (Cex) and cant angle. The dimensions to analyse the lateral effect on the track over broad gauge (BG) track [9][10][11][12][13][14]. Some of the considerations are shown in the table below which will help us to calculate resultant forces.…”

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.

“…So, skid plates should be sustaining any load coming through off road event or driving condition. There are challenges to develop the skid plates such as load how much load needs to consider, skid plate profile how to develop profile which sustain the desired load, design gaps what are assumptions to be considered when actual design gaps are not available between the skid plate and protecting part [6][7][8][9][10][11].…”

The objective of this paper is to show that how the development of skid plate can achieve without increasing the gauge and upgrading the material properties. There are certain factors which can influence the skid plate such as rail width, shape, ground clearance, attachment points, load coming on skid plate and the general shape of the object for which it is the skid plate's design and purpose is to protect (transfer case, fuel tank etc.).This document also covers the CAE procedure to evaluate performance of skid plate for structural integrity under static load condition for vehicles. Bead plays an important role to increase the structural stiffness but challenge is how to decide bead patterns and bead pattern can be achieved by using topography optimization approach. The skid plate should absorb the damage and protect underneath parts and protect vehicle function ability. This paper will demonstrate a few ways to achieve a successful skid plate design while gaining some other unexpected benefits described herein.
