ANALYSIS AND OPTIMIZATION OF CONNECTIN FIBER REINFORCED PLASTIC

Abstract

Connecting rod is an important dynamic link rod between piston and crank shaft. This undergoes a complex state of stress during working and adds to the problem in design for strength. Mostly connecting rods are manufactured using carbon steel and in recent days composite materials are finding its application in connecting rod. In the present paper a finite element model was developed to study the effects of various stress patterns on the design of the rod. To achieve the objective, connecting rod is modelled by taking the dimensions from actual component captured from a blue light scanner. The practical load-data points as a function of crank angle are directly collected from the four cylinder diesel engine. Simulation software is used to determine the pressure in the cylinder. The values of angular velocity and acceleration are calculated theoretically using analytical equations. Using the above data, static and dynamic finite element simulation is carried out successfully and connecting rod is replaced by carbon based composite material reinforced with silicon carbide. And it describes the modelling and analysis of connecting rod. Finite Element Analysis was carried out by considering two materials. The parameter like von misses stress, von misses strain and displacement was obtained from Abacus software. Over the past years, improvements in performance efficiency have been achieved by simplifying the design of the structural components and using composite materials to reduce the overall weight.
