Abstract

To enhance the accuracy of simulation for mechanical analysis of an assembled crankshaft often used in single cylinder, small displacement engines, it is important to make a detailed model of rolling bearings simulating physical phenomena such as deformation, contact, and damping. A rolling bearing model that permits simulation of three-dimensional contact considering elastic properties was developed, and the analysis accuracy was increased. By applying the rolling bearing model to the mechanical analysis of the assembled crankshaft, the correlation between the crankshaft displacement and the strain during actual engine operation was confirmed. As a result, it was confirmed that the rolling bearing model is practically accurate enough for strength computation in the design stage of the assembled crankshaft system.
