Abstract: In modern industries, commercial refrigerators play a major role in preserving food groceries, beverages, etc. Hence designing and analysis of these refrigerators to withstand given load has become a major concern in recent years. The objective of this dissertation was to analse and optimize the refrigerator shelf and to find maximum stress and deflections of entire refrigerator assembly for given loading and boundary conditions using Finite Element Method. First stage consists of Analysis and optimization of refrigerator shelf. Second stage consists of the Analysis of entire refrigerator assembly. While lifting the structure from one place to another place, structure has to be tilted to a small angle so that the structure sits firmly on the automated guided vehicle. Hence it is very important to find the critical angle of tilt for safe transportation and thereby preventing from a huge loss. Finally, Toppling analysis of entire refrigerator assembly was carried out to find the critical angle of tilt. In this critique, Pro/Engineer 3D CAD models of refrigerator shelf and entire Refrigerator assembly were imported to Hypermesh as an IGES format. The meshed finite element model with given loading and boundary conditions were exported to Finite Element Solvers (NASTRAN, ANSYS) to determine the maximum displacement, maximum stress and deflections at specified locations. Finally the model of refrigerator structure was exported to motion view in H3D format to carry out toppling analysis.
