Abstract
A random vibration test is important for confirming the safety of packaging on a truck bed during transportation. There are differences between the random vibration generated by the traditional method and the real vibration measured on a truck bed. Multiple studies have been performed to improve the generation of vibrations during testing. These methods are broadly divided into two categories: non-stationary and stationary. Since advantages and exist for both methods, they need to be compared under the same conditions. To date, there are no studies that compare stationary and non-stationary methods. Herein, seven different methods (both stationary and non-stationary methods) are used to generate vibrations. The generated vibrations are evaluated by statistics, the moving root mean square, and the kurtosis response spectrum. In terms of the kurtosis response spectrum, the kurtosis response method (a stationary method) is the closest to the real vibration, especially when the damping factor is low.
