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.

Element Analysis

There are many instances where creating finite element analysis (FEA) requires extensive time and effort. Such instances include finite element analysis of tree branches with complex geometries and varying mechanical properties. In this paper, we discuss the development of Immediate-TREE, a program and its associated Guided User Interface (GUI) that provides researchers a fast and efficient finite elemental analysis of tree branches. This process was discussed in which finite element analysis were automated with the use of computer generated Python files. Immediate-TREE uses tree branch’s data (geometry, mechanical properties and etc.) provided through experiment and generates Python files, which were then run in finite element analysis software (Abaqus) to complete the analysis. Immediate-TREE is approximately 240 times faster than creating the model directly in the FEA software (Abaqus). The process used to develop Immediate-TREE can be applied to other finite element analysis of biological systems such as bone and tooth.

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.

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 finite element models of the planar K-joint are established based on the finite element analysis software ANSYS. The bracing members are under the action of axial force and moment. Different rotational deformation values of the joint with different geometric parameters are reached with calculation and analysis. Results show that the deformation value approximate linearly increased with the increasing load of the bracing member. It also shows that the influence of the bracing member diameter and wall thickness is larger on rotational deformation values and the rotational deformation of the part of the K-joint is greatly influenced by the deformation of joint region.
