Railways provide a long and continuous journey for passengers and goods at an affordable cost. The rails and rail joints should be of high quality to ensure a safer transportation of people and goods. The tracks (rail) are made of alloys of iron and are fastened to other rails using fasteners. Nowadays, these fasteners are replaced with welded joints because of rising maintenance issues. Thermite welding is a globally adopted process for welding the rails. This article aims to best utilise the Aluminium composites for the welding of rails. The composites were prepared using stir casting route and a wear test was done on the casted samples to test their durability. Also, some of the mechanical properties of the composite material were found. The rail and track models were made and imported into ANSYS Finite Element Analysis software. The predicted results show that aluminium composites have considerable strength when compared to any other composite material.

In this paper, ANSYS, a finite element analysis software is used to simulate the change of temperature field in micro-hole processing with millisecond laser, which determines the diameter and depth of the hole drilled. The relationship between processing parameters and the hole size is plotted, so as to achieve size control of a micro-hole processing. Compared with experimental results, simulation is effective for laser processing of micro-hole and can be referenced to choose the best processing parameters.

Sg Iron

Steering knuckle is a prominent component of an automobile steering system. It is subjected cyclic loads from the suspension system during its service life. The Spheroid Graphite (SG) iron is the most commonly used material for manufacturing the steering knuckle. Fatigue behaviour is therefore a key consideration in its design and performance evaluation. Geometric modelling and stress analysis of such steering knuckle using finite element analysis software is carried out. Then the fatigue life of steering knuckle made from SG iron has been evaluated under the different load conditions and the results have been compared.

The Relationship

This paper proposes a computation method using the equivalent magnetic circuit to analyze the driving force for the non-contact permanent magnet linear drive system. In this device, the magnetic driving force is related to the rotation angle of driving wheels. The relationship is verified by finite element analysis and measuring experiments. The result of finite element simulation is in good agreement with the model established by the equivalent magnetic circuit. Then experiments of displacement control are carried out to test the dynamic characteristic of this system. The controller of the system adopts the combination control of displacement and angle. The results indicate that the system has good performance in steady-state error and response speed, while the maximum overshoot needs to be reduced.

The Finite Element Model

The aim of this paper is to design and fabricate a star die and a cylindrical die to produce a star shape by redrawing the cylindrical shape and comparing it to the conventional method of producing a star cup drawn from the circular blank sheet using experimental (EXP) and finite element simulation (FES). The redrawing and drawing process was done to produce a star cup with the dimension of (41.5 × 34.69mm), and (30 mm). The finite element model is performed via mechanical APDL ANSYS18.0 to modulate the redrawing and drawing operation. The results of finite element analysis were compared with the experimental results and it is found that the maximum punch force (39.12KN) recorded with the production of a star shape drawn from the circular blank sheet when comparing the punch force (32.33 KN) recorded when redrawing the cylindrical shape into a star shape. This is due to the exposure of the cup produced drawn from the blank to the highest tensile stress. The highest value of the effective stress (709MPa) and effective strain (0.751) recorded with the star shape drawn from a circular blank sheet. The maximum value of lamination (8.707%) is recorded at the cup curling (the concave area) with the first method compared to the maximum value of lamination (5.822%) recorded at the cup curling (the concave area) with the second method because of this exposure to the highest concentration of stresses. The best distribution of thickness, strains, and stresses when producing a star shape by
