Experimental Verification On The Effectiveness Of Random Vibration Testing With Controlling Acceleration And Velocity Kurtosis, Daichi Nakai, Katsuhiko Saito Nov 2021

Experimental Verification On The Effectiveness Of Random Vibration Testing With Controlling Acceleration And Velocity Kurtosis, Daichi Nakai, Katsuhiko Saito

Journal of Applied Packaging Research

Random vibration tests for packages are conducted to confirm the safety of these packages during shipping. In our previous study, a method of generating the random vibration controlling the power spectral density and kurtosis of acceleration and the kurtosis of velocity was proposed. The aim of the present study is to verify the effectiveness of the proposed method. Three vibrations were generated in this study and compared with the real vibration, which replicates the truck bed. In the first case, control of the acceleration and velocity kurtosis was neglected. In the second case, the vibration controlling the acceleration kurtosis was …

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 …
