Book Description
The Armored Vehicle Launched Bridge (AVLB) is a folding bridge that was fielded in the early 1960's as the Army's standard heavy assault bridge. The bridge is rated for normal crossings of military load classification of 60 tons (MLC 60) over a maximum gap of 60 feet and a vehicle speed of 25 mph. The System Simulation and Technology Division, AMSTA-RY, was tasked by the Systems Engineering. Directorate, AMSTA-U, to perform an anlaysis of the AVLB over a 60- foot gap while an M1A1 crosses it. The objective of this project was to perform a finite element analysis (FEA) of the whole AVLB to determine high-stress areas of concern. Finite Element Analysis, AVLB.

Book Description
An Armored Vehicle Launched Bridge (AVLB), with a span of 60ft (18.29m), capable of supporting tracked and wheeled vehicles of up to military load class-60, is required to meet the assault gap crossing needs of the Fleet Marine Force (FMF). The AVLB will be used as a rapidly employable, short-gap, assault crossing bridge, capable of spanning road craters, anti-tank ditches, partially blown bridges, railroad outs, canals, rivers and ravines up to 60ft (18.29m) in length. The AVLB fulfills this requirement for assault crossings where air or ground superiority has not been attained. The AVLB will be carried and launched from the chassis of the M48A5 or M60A1/A2 battle tank (minus turret), the selection of which will be determined by availability, costs and other considerations at the time of procurement. The desired Initial Operational Capability (IOC) for this equipment is FY89. (Author).

Book Description
Due to increased vehicle weight and the need to increase load carrying capacity, interest has been shown to increase the AVLB's load rating without any design changes. This may have an adverse effect on the AVLB's fatigue life.

Book Description
The current Class 60 armored vehicle launched bridge (AVLB), with an overall length of 63 ft, is capable of carrying Class 60 (military load classification MLC - 60 tons) tracked and wheeled loads over a 60-ft-wide gap. The heavier, wider M1A1 main battle tank (Class 70 load) can cross the AVLB over a 50-ft-wide gap with precautions. Several modifications were proposed to upgrade a number of AVLBs from Class 60 to Class 70 for the 60-ft clear span crossings. The objective of the work was to conduct necessary mechanical tests on selected AVLB components to obtain pertinent data to verify their load carrying capability and the proposed modifications. Various AVLB components were cut or removed from several AVLBs as samples for a variety of mechanical and special tests. Special test jigs were designed and built to test the samples of the components on the testing machine. Failure analyses were performed on the components that failed during the special tests or the fatigue tests of the modified AVLBs undergoing the simulated crossings. Two Class 60 AVLBs were converted to Class 70, with extensive modifications to the bottom chords, and then were tested. One of them was deliberately tested to failure by static overloading to observe the mode of failure. The bridge buckled in the top chords at about 190 tons. The modified bottom chords did not fail by cracking, indicating the success of the Class 70 modification program to upgrade the AVLB.
