DESIGN, CONSTRUCTION AND TESTING OF MAGNESIUM WISHBONE BOX TRAIL FOR THE HOWITZER, LIGHT, TOWED 105MM XM102,
Abstract
The desirability of reducing the weight of the experimental al gun trail was recognized. Given the loading conditions, the al design was adapted to mg. Section thicknesses were changed to take into account the differences in mechanical properties between 5083 alloy al and the ZE10A-H24 mg alloy used. Certain other structural design changes were made to achieve more efficient use of metal and to improve fabricability. Engineering layout, and detail and assembly drawings were prepared. A prototype of this design was fabricated, welded, stress relieved and machined. An approved protective finishing system was applied. This magnesium gun trail weighs only 309 pounds vs the aluminum weight of 413 pounds. Based on static loading tests performed, the amount of deflection and permanent set were only slightly greater than in the alversion. The strength, stiffness and damping characteristics of the mg design meet requirements. (Author)
