Review on Metal Bellows Used in Expansion Joints
Abstract: Metallic bellows are manufacturing expansion joints commonly used in aerospace, chemical plants, power system, heat exchangers, automotive vehicle parts, piping system, petrochemical plant, refineries, etc., which are subjected to high temperature, pressure and corrosive environment. Bellows are special structures that require high strength as well as good flexibility. Most industrial piping system often suffer excessive deformation, displacement, heat expansion, vibration, and other causes which are responsible for the failure. During …

Fin-Set Materials Analysis for Heat Removal Utilizing ANSYS
Abstract: Present paper deals with the effect of fin material on heat transfer from fin for electronics device cooling. Electronic tools discharge heat in the course of the work; that discharged heat should be removed either by passive or active ways. Current work stresses on passive (natural) way of cooling. Natural cooling can be done either by free air or fin. Different types of fin materials have been studied in the …

Fillet Weld Analysis Utilizing Ansys: Study of Loading Condition
Abstract: Present paper represents the stress and strain generated at the root and toes of the fillet weld. A T-joint fillet weld has been taken into consideration. First a model of the T-joint fillet weld has been moulded. Different aspects of weld, like their types, geometries, boundary conditions have also been reviewed in short. Finite element (FE) tool Ansys has been used to simulate the three-dimensional T-joint fillet weld. Different methods …

Design and Simulation of PID Controller for Two Link Robotic Arm
Abstract: This paper deals with the design of two link robot arm control methodology using PID controller. A two degree of freedom (2DOF) robotic arm is designed using a PID controller and simulated in MATLAB/SIMULINK platform. A good performance of a robot requires the consideration of efficient dynamic models and sophisticated control approaches. The dynamic model is derived from the general Lagrange equation. The simulation of two link manipulator (TLM) has …
