Abstract
The padded shoulder of the M35 TAV (prototype load carriage vest) is to be replaced with three inch wide flat webbing to provide a lower profile and improve compatibility with the padded shoulder strap of the CTS rucksack. A biomechanical comparison of these two shoulder designs was performed to ensure that this change will result in a net improvement in the TAV design. The Load Carriage Simulator was used to compare the two shoulder designs. It consists of a representative 50 percentile male torso, anthropometrically weighted and covered in an artificial skin analogued mounted on a programmable displacement table. During simulated running, (10km/hr), both TAV designs were loaded with 141 N and the contact pressure distributions were measured with a Tekscan FScan system at four locations: left anterior shoulder, left posterior shoulder, left axilla and left hip. In a second test, the two shoulder designs were assessed for pressure distribution and physical compatibility when worn under a loaded (231N) CTS Rucksack. The webbed shoulder design performed as well as a padded shoulder did in distributing the load onto the upper shoulder region. A flat webbing design also proved a flatter profile under the shoulder strap of the CTS rucksack. TRUNCATED
