Static Structural Analysis and Optimization of Pneumatic Compressor Connecting Rod

The reciprocating engine mechanism is widely used as a suitable mechanism for pumps and compressors. In this study, finite element analysis is carried out for the connecting rod using ANSYS under static load condition. Connecting rod is a main component which connects piston and crankshaft. This all together forms a driving mechanism. The Power Transmission of this mechanism is in push& pulls form. Basically, connecting rods are designed to sustain higher bending stress. These stresses are due to loading at TDC. This paper contains the static analysis and optimization of pneumatic compressor connecting rod. The existing connecting rod having weight 272.79 gm. Design of existing connecting rod done by using CAD package CATIA V5. FEA done using ANSYS package. FEA help in identifying strain and stress occurs in connecting rod. Optimization is done using manual removal. According to FEA result, machining is done. After optimization, connecting rod weight is 256.51 gm. The surface preparation is done before installing strain gauge on component. The Experimentation is done on optimized connecting rod by testing on UTM by compressive force at Piston End.
