Noise and vibration aspects on railway goods transportation Carlsson, Ulf
Series: Rapport ; 0506EPublication details: Stockholm Järnvägsgruppen KTH, 2003Description: 25 sSubject(s): Online resources: Abstract: The cost for goods damaged during transportation is for most companies unnecessary high. For this reason a high goods comfort to a reasonable price is one important component in a goods transportation system able to attract customers. Shock and vibration is the single most important cause of damaged goods and must be considered when goods comfort is discussed. A comparison between railway, air and road transportation shows no drastic differences in goods shock and vibration levels. Negative for railway goods transportation is, however, the fact that the goods securing rules are more restrictive for railway transportation than for the other transportation systems. The most important causes of goods damage during railway transportation are improper goods handling during loading, unloading and switching. Hence, it is an important task for further studies to develop improved handling routines that prevent goods damages. Monitoring the comfort of sensitive goods is a method that would increase the competivity of the railway transportation system. A comfort monitoring system would improve the quality image of the transportation system. It would provide valuable knowledge on goods damage mechanisms and increase the possibilities to prevent damages. It would make it possible to make decisions on damage responsibility issues. Finally a comfort monitoring is likely to increase the comfort awareness in the whole transportation system. Monitoring climate factors such as temperature is straight-forward. Shock and vibration monitoring require, however, a number of research tasks to be solved. The most important and probably most difficult of these is to find practical methods to measure accelerations representative for the goods shock and vibration exposure. Another positive measure is to provide the customers with recommendations and advice regarding goods packaging. This will further improve the quality image and the customer confidence in the transportation system.The cost for goods damaged during transportation is for most companies unnecessary high.
