Overview
The technology described in this article was successfully used in the Ground Recorder System to achieve a very high measurement of dynamic range for a recent NASA project. This technology is now integrated into the CoCo-80X portable hardware platform by Crystal Instruments.

Read MoreMultiple shaker systems are typically used for vibration testing when the unit under test (UUT) is too long or too heavy to test with a single shaker. This approach overcomes the limitations of high drive requirements with a single shaker test. Multiple shaker systems also allow the UUT to be tested in various configurations and directions in the horizontal and vertical orientations.
Read MoreGround Vibration Testing (GVT) includes the modal analysis of an aircraft and its sub-assembly components to analyze and detect any changes to their structural properties.
Read MoreShaker applications involve the use of many attachments to the shaker’s armature. Head expanders, fixtures, adapters, and devices under test (DUT’s), all attach to the shaker for the testing process. While it is common to simply consider the added mass of these components, their deformation during vibration can also have a significant impact on the vibrations experienced at any certain point of interest.

Read MorePickleball noise is comprised of several interactions, one being the paddle impacting the ball and another being people cheering and shouting. The paddle impact noise is one of the issues the industry has faced, and some paddle manufacturers are claiming quiet noise characteristics of their paddles.
In this opportunity, we used the Crystal Instrument’s CoCo-80X to characterize the noise from several paddles for acoustic comparison. The equipment consisted of three (3) microphones mounted on an arch boom and seven specimens to be tested (including different paddles). The testing was done inside the MD Acoustics, LLC’s anechoic chamber at the facilities in Gilbert, AZ.
