| Outline of Final Research Achievements |
Vibration tests of packaged freights are conducted before distribution in many industries in order to prevent troubles during transportation. In order to improve the test accuracy, vibration behavior during transportation and during test was studied, focusing on packaged products in a box. By measuring the vibration of products in the x, y, and z directions during the test, the existence of the vibration of products in the non-excitation direction was clarified, which leads to deterioration of the test accuracy. As a countermeasure, a conventional method to derive test conditions from transportation vibrations was improved in order to take into account vibration of products not only in the excitation direction but also in the non-excitation direction.
