A Method For Generating Random Vibration Using Acceleration Kurtosis And Velocity Kurtosis, Daichi Nakai, Katsuhiko Saito
Journal of Applied Packaging Research
Random vibration tests for packaging are conducted to confirm safety during shipping by truck. However, there is a difference between the traditional random vibration tests and the real vibrations on the truck bed. One reason for this difference is the shock caused by road roughness. Hence, many studies have been conducted to improve random vibration testing. In these studies, the root mean square, power spectral density, kurtosis, and probability density of acceleration are considered. In this study, we show that the kurtosis and probability density of velocity are also important factors for such tests and propose a new method for …
