Transport vibration has long been recognized as a significant source of potential damage to products in distribution. In order to optimize packages for vibration protection, packaging engineers must understand and quantify this vibration and be able to simulate it in the laboratory. Random vibration testing, which provides the best laboratory simulation, started being used in packaging laboratories in the late 1970s. Initially, the spectrum shapes and levels were based on simple estimates or crude acceleration data, as at that time there was no way to accurately measure transport vibration in the required format. The first truly portable field data recorders were introduced in the late 1980s and currently have the capability to provide complete and meaningful information. As a result, appropriate technology now supports all portions of the process, from measurement and analysis, through laboratory test simulations. In recent years, many researchers have studied the worldwide transport vibration environment and its simulation in the laboratory. As these studies become more sophisticated, it is being recognized that improvements can be made to the traditional single‐spectrum, power spectral density (PSD) approach. There is increasing recognition of the non‐stationary aspects of the environment, as well as the fact that a variety of shocks are often superimposed on the vibration. The papers in this special edition illustrate not only the current established practices in the measurement, analysis, and laboratory simulation of transport vibration but also the new concepts regarding both sources and treatment of the data, as well as possible improvements to laboratory simulations.
