U.S. Army Materiel Command (AMC) Field Assistance in Science and Technology-Jr.(FAST-JR) Project: Arctic Troop Cover (ATC)

摘要

The present troop cover for the 2.5-ton (M35A2) truck is an outdated design thatis heavy and difficult to handle in the extreme cold weather of the arctic environment. The 2.5-ton truck is being replaced by the 5-ton (M923/ M939A2) truck, which at present has no provision for an arctic troop enclosure. There now exists a need for an arctic specification troop enclosure for the 5-ton truck that does not compromise the 5-ton truck's cargo-carrying capability. A prototype arctic troop cover (ATC) has been fabricated at the Directorate of Logistics (DOL) Maintenance Facility located at Fort Richardson, AK. The prototype ATC is attached to the 5-ton truck through a six-point attachment scheme. The authors were tasked by the U.S. Army Materiel Command (AMC) Field Assistance in Science and Technology (FAST) via the Alaskan Command (ALCOM) Science Advisor to determine whether or not the scheme for attaching the ATC to the 5-ton truck bed was sound from a structural viewpoint under a worst-case rail impact loading situation. The attachment scheme proved to be structurally deficient for the loading case considered. The analysis findings and recommendations for correcting the deficiencies are documented in this report.
