Unexpected dynamic behavior in machines often results in increased              vibration and noise, reduced machine reliability and life, and loss of          precision.  All of this has a significant impact on                             overallproductivity.  A clearer understanding of the dynamics of                machine components can be attained through better modeling than is              currently available.  Key areas for modeling research are flexibility           of system elements, clearances in connections, and inherent                     nonlinearity of these effects.  Theoretical studies arecomplemented by          experimental investigation.  Results are incorporated into                      computeraided design systems for use in the industrial environment by           the design engineer.
