Automated Generation of Crankshaft Dynamic Model to Reduce Engine Development Time

One of the ways to represent the crankshaft in a 3D engine dynamic simulation is by using structured model consisting of nodes and binary elastic elements.

The paper presents a methodology for automatic generation of this kind of models, starting from CAD data.

The main advantage of the method - implemented as a software tool - is a significant reduction in time to model the crankshafts, and hence the overall project time. The calculation results show a good correlation with those obtained by commonly used FEA software.
