In today’s world, aluminium and its alloy is showing promising characteristics for replacing other materials due its excellent properties like light weight, corrosion resistance, high strength and toughness. Conventional welding for these materials creates some challenges like porosity, hot cracking and void formation. Ultrasonic welding gives some ultimate solution to these problems as the material experience only 30% of its melting point temperature. Ultrasonic welding is a creative system for joining metals and composites rapidly and safely owing to a high-frequency vibration consolidated with pressure. The process has a widespread application in electrical, automotive, aerospace, medical and packaging industry. In the present research work, a numerical model is proposed for the evaluation of heat generation due to deformation and friction during welding. The developed model is equipped for predicting the interface temperature and stress distribution during ultrasonic welding and their impacts on sonotrode, anvil and welded parts. The effect of tool (sonotrode) shape also studied. Response surface methodology (RSM) with Box-Behnken design has been implemented to design the experimental setup and establish a co-relation between process parameters viz. pressure, amplitude and welding time with the output response as tensile strength. RSM is coupled with desirability function is utilized to optimize the parameters for a desired tensile strength of the joint. The result of numerical model is compared with the experimental value and found to be in good agreement.

The purpose of this project is to optimize the design, dimensions along with changing in material of the bracket structure to ensure the structural fatigue life increase along with reduction in stress and displacement of the component. Optimization study of components gives a great opportunity for material saving which leads to save cost and man power. The major bracket design parameters were explained in detail and the bracket configuration has been described. Different types of loads acting on the aircrafts bracket are determined and the moments, displacements, etc., are also determined. The bracket structure was also explained and functions of each component and their arrangement are also studied. The methodology of finite element method and the detailed description about various FEM tools have been studied and implemented in this work. The procedure of finite element method was followed to analyse the model. The analysing part of this project is done using CAE tool package and the results were discussed. In this Project, we designed Aircraft engine bracket using CATIA V5 and carried out linear static analysis using MSC Software. For Pre-Processing used MSC PATRAN and MSC NASTRAN for solving followed by Fatigue calculations.
