Continuing from Part 2 of this series...after establishing improved confidence in identifying tire effects on vehicle ride quality, I finally decided it was time to replace my tires all together. To document before… read more →
Continuing from Part 1 of this series, intuitively, one could expect that the resonant tire frequency in the data would change with changes in vehicle speed. The slower the speed, the lower… read more →
When we describe transport vibration, we typically use Power Spectral Density (PSD) plots to define meaningful characteristics (frequency bandwidth, amplitude within discreet frequency bandwidth bins, and overall spectrum intensity). Another… read more →
When transporting products from one location to another, we use packaging materials and technologies to protect them from the various hazards present within the distribution environment. Some of those hazards… read more →
