Comparison of mechanical impedance methods for vibration simulation [PDF]
36th Structures, Structural Dynamics and Materials Conference, 1995 The work presented here explored the detrimental consequences that resulted when mechanical impedance effects were not considered in relating vibration test requirements with field measurements. The ways in which these effects can be considered were evaluated, and comparison of three impedance methods was accomplished based on a cumulative damage ...
