Modal analysis for small engine crankshaft

This thesis consists of finding the mode shape and natural frequency of a 4 stroke motorcycle engine crankshaft. The test is done in both simulation and also experimental using a simple test rig. The crankshaft is modeled using Solidworks computer aided design (CAD) software and simulation analysis...
