NMSBA High Frequency Modal Analysis of a Solid Metal Cylinder Using a Polytec 3D Scanning Laser Vibrometer.

摘要

This memo documents the results and methodology of the high-frequency modal test performed on a solid metal cylinder, provided by Vibrant Corporation, in April 2015 at Sandia National Laboratories in the Component Dynamics Laboratory. This work extends the FY14 project. The purpose of this extension test was to measure mode shapes of 3 units between 140 kHz and 160 kHz to determine if the shape order remains consistent from unit to unit.
