“…H. Gandhi et al [4] proposed an analytical and empirical model to estimate the top roller position explicitly as a function of desired radius of curvature for three roller cylindrical bending of plates. Top roller positions for loaded radius of curvature are plotted for a certain set of data for center distance between bottom rollers and bottom roller radius.…”

This paper describes a comprehensive review of major published research work performed on three as well as four roller bending process. Based on the literature, further research scope is identified. The present literature reveals that there is a further scope to model the three roller bending process in a generalized and simplest form includes various parameters viz geometrical, process, and material parameters, which will help to produce sheet metal parts to precise shape with smooth surface finish and good dimensional accuracy.

A new downscale test rig is developed for investigating the contact between the wheel and rail under impact-like loading conditions. This paper presents the development process of the setup, including review and synthesis of the potential experimental techniques, followed by scalability, mechanical and operational analysis of the new setup. The new test rig intends to remedy the lack of dynamic similarity between the actual railway and the existing laboratory testing capability, by taking into account the factors that contribute to high-frequency dynamics of the wheel-track system. The paper first reviews the functionalities of the existing test techniques in the literature. Based on this survey, the category of the scaled wheel on the rail track ring is chosen. Afterwards, three potential alternatives are identified under the chosen category and the optimum mechanism is achieved through finite element modelling and analysis of the structures. A downscale test rig, consisting of multiple wheel components running over a horizontal rail track ring, effectively fulfilled the requirements needed for analogical testing of the wheel-rail contact behaviour. The new test rig is a unique experimental setup due to the involvement of high-frequency dynamic vibrations in the wheel-track system and analogy of the incorporated elements and loading to those of the real-life system. This paper further presents the results of some real experiments carried out using the newly-built setup to support substantial ideas behind its development.

Abstract-Roller bending process is used to transform a sheet or plate into hollow cylindrical shapes implementing plastic deformation techniques. Cylindrical and conical shells are the basic elements used for the various engineering applications like cylindrical tanks, boiler chambers, heat exchanger shells, pressure vessels and structures. In these cases, it is important to bend the sheet safely and working for longer life. In bending operation a metal sheet is subjected to sequential bending stresses for different position of top roller. Advanced techniques are used for verification of stress values up to ultimate tensile strength of material. Failure of material is detected at UTS value by visualizing the cracks.
