THE MAXFORCE® CONCEPT- CONSIDERING DYNAMIC FORCES DURING TRANSPORT OF DANGEROUS GOODS

A new container concept called the MAXFORC® concept is presented which has been developed for transporting dangerous goods. For the first time, dynamic loads have been considered as design requirement for the design of ISO freight containers. Various international rules and regulations have been compared regarding the dynamic load requirements for ISO freight containers and enormous differences were observed. While various regulatory frameworks like the CSC (Convention for Safe Containers) or ISO 149611 are satisfied with ~tatic loads: 2 g (corresponding to 0.8 g dynamic) in the construction of freight containers, the ST-2 recommend 5 g dynamic and the US CFR 10 g dynamic (without 16Hz low-pass filtering) as design criteria. Transport is a dynamic process. STM have based its design requirement for the MAXFORC® container concept on various switchyard ram tests, a drop test and on numerical computer simulations. STM propose for routine conditions of transport (incident free) a dynamic design load in longitudinal direction of 6 g and for normal conditions of transport (minor mishaps) dynamic design load of 9 g.
