Modeling a Clamped Boring Bar using Euler-Bernoulli Beam Models with Various Boundary Conditions

This paper addresses modeling of a clamped boring bar using Euler-Bernoulli beam theory. Euler-Bernoulli beams with a number of different boundary conditions were used to model a clamped boring bar. Estimates of the boring bar's natural frequencies and mode shapes were produced with each of the boring bar models. The estimates produced by the distributed-parameter system models are compared with eigenfrequencies and mode shapes estimated based on experimental modal analysis of the actual boring bar clamped in a lathe.
