A Study on the Journal Orbits in the Big-End bearings of Engine Connecting Rod

엔진 커넥팅로드 대단부 베어링의 운동 궤적에 관한 연구

The motion of dynamically loaded journal in the connecting rod big-end bearings is considered and then equations of motion are derived. Dynamical characteristics of big-end bearings are derived by perturbation method and linearized spring and damping coefficients are calculated. Numerical intergrations of equations of motion ure performed by $\rho$-family method. This paper gives various journal orbits in a big-end bearing depending on external force cycle and bearing parameters
