Abstract
<jats:p>Now a days we find most of the fire accidents occurred are due to the leakage of gas cylinders which explode and cause lots of damage not only economically but also result in severe injuries and in some cases even human loss as well. Hence a source or device is needed for testing the leakage of gas in a cylinder within the industry before it is delivered to the consumer. One such type of device is the Portable Gas Leak Tester. The main objective of the project includes Modelling and analysis of a Portable Gas Leak Tester. In the present work, an attempt is made to evaluate the performance of the PGLT model through FEA. The PGLT model is the assembly of various sub parts like O-ring tester upper body, tester lower body, tester nozzle, holder, cantering cone, O-rings, indicator cover. Static analysis and Dynamic analysis is performed on two different models, one is the model assembly of parts made by the materials SS 316, PVC and the other is the model assembly of the parts made by the materials SS 316, PVC, Al6061 materials to evaluate the performance of each model under same load conditions such that some parts made by SS 316 replaced with Al 6061 which reduces the weight and cost of the model. Comparison is done for the two models based on the materials used for the parts and concludes with the better model. Modelling is done using Pro/Engineer (Creo Parametric 2.0) software and Analysis is done using ANSYS.</jats:p>
