STRUCTURAL ANALYSIS AND OPTIMIZATION OF THE HATCHED DOOR OF THE SUBMARINE

Bhaskar Patil, Ravi G Lingannavar

The submarine door mechanism is being analyzed for the identification of possible failure situations. An effort has also been made to give suggestions regarding the dimensions of the door model of submarine for further improvements. This will be helpful to the company to fabricate and also to show the results of the analysis to prospective customers. Purpose of the analysis is detect any flaws in the design stage can be identified and corrected in the analysis stage. Analysis stage acts as a prototype building stage where in the original is modeled and analyzed. The stress developed can be understood and suitably reduced by increasing or decreasing the dimensions, using a better material. The stress distribution can be understood and the maximum and minimum stress acting on the material can be estimated. In this project an effort has been made to carry out the analysis of “submarine door mechanism”. The project requires a basic knowledge of the analysis software and the working of the mechanism this is a complicated task, so to solve such problem COSMOS is the most preferred software tool, which has no boundary limit for analysis. Here Structural type of analysis carried out it includes a general overview of the submarine door mechanism CAD systems, FEM, the introduction to COSMOS. The final section of the documentation deals with the comparison of manual design results with the results obtained from the use of analysis software and if stresses result vary and factor of safety is high then we may require to go for optimization of particular part.
