Paper IV (iv) Non-Linear Transient Analysis of Diesel Engine Connecting-Rod Bearing with Circular and Non-Circular Profiles

In this paper, the dynamic performance of the Ruston and Homsby VEB diesel engine connecting-rod bearing is analyzed. The effect of cavitation is considered by using a cavitation algorithm, which mimics JFO boundary conditions. The effect of mass inertia is accounted for by solving coupled nonlinear equations of motion using a fourth order Runge-Kulta method. The performance is predicted for a bearing with a circular profile and two noncircular profiles, viz, worn circular and elliptical. For the circular bearing the results are compared with various published results and the predictions for the non-circular bearings are compared to those with a circular profile.
