The major source of noise pollution was an internal combustion engine. Henceforth, the design of the engine exhaust system was a tough challenge for automotive industries. The mufflers have been used to moderate the exhaust noise from the engine to the neighboring atmosphere. So in domestic as well as the industrial application, it is required to reduce noise levels to prevent human hazards. The performance of muffler is measured in terms of transmission loss. The transmission loss of reactive muffler is depending on its geometry. This article describes the effects of pores at the inlet pipe and outlet pipe of the reactive muffler on its performance capacity at a target frequency. It is found that the muffler performance is dependent on the number and position of pores. The single chamber and double chamber reactive mufflers are used for the study. The numerical analysis is performed by COMSOL Multiphysics software. The numerical analysis result of the different models of the muffler is compared with experimental analysis. The purpose of the study is to investigate the effect of pores in inlet and outlet pipe to maximize the TL at the target frequency of reactive muffler.

Abstract The failure of dies and its repairing options are very important in die casting industries. Of all the casting processes available, pressure die casting finds wide applications in large scale production of complex shaped objects with intricate geometries that require good surface finish and dimensional stability. The cooling system employed in the die not only facilitates proper solidification of the cast components but also helps in maintaining the die temperature and controlling the stresses generated during the cyclic operation. The research work focuses on designing a die of H13 material for ADC12 cast part that is to be operated on 160 Tonne Cold Chamber HPDC machine. The effect of cooling system location on the stresses produced in die is analysed and their optimum location is determined by ANSYS. Further, filling simulation of the modified design was carried out and minor modifications are made to optimize the filling operation using MAGMA Software. The research work proves to be useful in increasing the die life by considering the optimization of cooling channel position along with the gating system design in the design stage.

Abstract Preceded by unbalance, misalignment is the second major mechanical fault in rotating machine applications. In spite of using modern alignment techniques like laser alignment tool, the accidental misalignment arises over a period of continuous operation due to many reasons. This can lead to excessive forces on components of rotating systems, which ultimately greatly influence on its vibration spectrum. The study presents the results of Harmonic analysis of the Aluminum (Al) shaft rotor bearing system with rigid coupling, under parallel misalignment, using FEA. It show-cases vibration spectrum due to the misalignment. The results are compared with experimental results based on FFT analyzer for different sub critical speeds. Misalignment effect at coupling location is simulated using nodal force vector. The force vector is found using coupling stiffness matrix, derived from geometrical and material properties and instantaneous parallel misalignment between the two coupled shafts. Based on the FEA and experimental results, parallel misalignment in the shaft rotor system can be predicted almost at all speeds by observing 2X characteristics frequency of operating speed. However to diagnose the nature of misalignment, the knowledge of natural frequency of the system plays a crucial role. It facilitates determination of other dominant characteristic frequencies. An FEA approach is proposed for the first time for determination of magnitude and harmonic nature of the misalignment excitation of the system with rigid coupling
