Dynamic Behaviour of an Elastic Connecting–Rod Bearing – Theoretical Study 830307

The dynamic behavior of an elastic connecting-rod bearing is studied using an iterative method. Short bearing approximation for Reynolds’ equation and plane elasticity relations for the bearing housing are used for this study.
The locus of the shaft center in the bearing is calculated for the dynamic loading conditions of a connecting-rod bearing. Instantaneous elastic deformations and pressure distributions are given for different values of the load (or time). Variations of minimum film thickness, torque and flow rate versus shaft rotation are compared with those obtained for a rigid bearing housing and under the same dynamic conditions.
