Abstract

This research involves major areas of the connecting rod design that include computer simulation, the use of laboratory experimentation and consideration theories of failure. There is prediction of dynamic forces and internal stress resultant acting on the connecting rod from PROTON Wira engine. An MSC.ADAMS model of the crank, connecting rod and piston were built in order to predict the dynamic loads acting at the little and big end of the connecting rod. Then, MSC.ADAMS can be used to obtain the variation of quantities such as angular velocity, angular acceleration, and force in x-axis and y-axis. The connecting rod direction of motion must be identifying to make sure the stress is acceptable due to the force. Then, the predicted loads were used as inputs to a finite element model by using COSMOSXpress.ln this part of the research, there is experimental work needed to determine the mass moment of the connecting rod and compare it with theoretically determined values. The factor of safety was used in this work to quantify severity of the applied stresses with respect to the available strength.
