MECHATRONIC ANALYSIS OF A COMPLEX TRANSMISSION CHAIN

Mechatronic models of complex mechanical systems allow to study the contribution of each component to the overall system performance. Reliable simulators can be assembled, that can be used to test alternative choices made at component level. In this paper reference is made to a complex transmission chain used to actuate the work-table of a large size machine tool. A linear model is first derived and a simple procedure is proposed to quantify the contribution of each compliant element to the first vibration modes of the transmission. Then a detailed simulator of the transmission chain, assembled in the Dymola environment, is described and its remarkable ability in reproducing the experimental data is demonstrated.
