Book Description
In addition to the muscular effort required to carry a load, it has been found that the horizontal reaction force acting in the lumbar area is a major factor limiting the load carrying capacity of soldiers. Load transfer to the waist is an effective means to reduce high levels of contact pressure occurring at the shoulder straps and has been shown to reduce rucksack palsy incidence. In this study, an anthropometrically correct male manikin was split in the transverse plane at the level of the navel and instrumented with a six degree of freedom load cell to allow determination of the rucksack load applied to the shoulders & upper torso, independent of the load applied to the hips and lower trunk. Tests were conducted to determine the load transfer characteristics associated with adding lateral stiffness rods to the rucksack. Results are presented regarding the effect of the rods on reducing the vertical load applied to the upper back & shoulders.

Book Description
The objective of this study was to conduct a standardized assessment of the Clothe the Solder (CTS) integrated load carriage system (LCS) pack, final design, on a computerized load carriage simulator. Specifically, the simulator measured variables which assess the load control & load transfer capability of the CTS integrated LCS pack. These aspects of pack design consisted of several displacement, force, moment, & pressure variables that had been validated on previously tested systems where simulator outputs were compared to assessments by experienced users during human trials. The CTS final design pack was evaluated without the CTS tactical assault vest. The simulator consisted of interchangeable anthropometrically weighted manikins covered with a skin-like surface, driven by computer controlled pneumatic activators programmed to elicit a walking displacement pattern. A trial consisted of measuring inertial properties & dimensions, loading the pack with a 25 kilo payload, mounting the pack, and balancing the moments. Five intervals of 10 seconds of data were recorded over a 1200 second period. By this approach, the pack was assessed on the initial setup and after a sustained period of walking. A pack stiffness jig was used to examine the resistance of the pack frame to motions in three planes. The CTS rucksack performance was compared to previously validated variables for load control & load balance from the simulator.

Book Description
The purpose of this study was to provide an overview of contributions by biomechanical testing to the design of the final Canadian Clothe the Soldier (CTS) load carriage (LC) system. The Load Carriage Simulator and Compliance tester were used during design of the CTS system for evaluation of: three fragmentation vests seven Tactical Vests and three iterations of the rucksack. Test data were compared to a data pool of previously tested systems. Results indicated that the objective measures helped the design team by: (1) understanding the consequences of various design changes; (2) predicting soldiers' responses to design changes in pressure, force and relative motion; (3) comparting this system objectively to other systems; and (4) providing information quickly so that ideas could be incorporated into the next design iteration. It was concluded that objective assessments added valuable information not easily interpreted from human trials. However, objective assessments cannot replace human trials for feedback on functionality and features.

Book Description
The objective of this study was to conduct a standardized assessment of the CTS prototype modular (M1) pack on a computerized Load Carriage (LC) Simulator. Specifically, the LC Simulator measured variables which assess load control and load transfer capability of the M1 pack. These aspects of pack design were comprised of several displacement, force, moment and pressure variables that had been validated on previously tested systems where LC Simulator outputs were compared to assessments by experienced users during human trials.

Book Description
This report represents the User's Manual for the 3D dynamic load carriage simulator and automated test cell. Contained within this report are the hardware and software components in addition to instructions for users to run the system. If the system is ever moved to a new location, this manual must be taken with it for set-up and data acquisition. The changes to the automated programmable motion control system have created a number of functions not possible with the previous system. These functions include: (1) highly repeatable motion profiles independent of the operator: (2) determination of the system stiffness under dynamic conditions: (3) provision for quantitative validation of models of load carriage devices: (4) determination of the frequency response of LC suspension systems and (5) creation of an automated test cell requiring minimal operator expertise and low cost for possible sale to support other countries modelling efforts.

Book Description
Many NATO nations have soldier modernization programmes that aim to equip soldiers with fully-integrated state-of-the-art technologies that will enhance the five NATO soldier capability areas: lethality, protection, mobility, sustainability, and command and control. Military load carriage systems (LCS), which include clothing and personal areas. In particular, LCS are critical to soldier mobility and sustainability, and ultimately, to soldier performance and survival on the battlefield.

Book Description
This summary provides an overall perspective of progress throughout all contracts within two Canadian Forces soldier modernization programs: the Integrative Protective Clothing & Equipment (IPCE) project and the Clothe the Soldier (CTS) Project. Each of these projects is described briefly and relevant outcomes are identified. The first three phases concerned a contract on the research & development of an Advanced Personal Load Carriage Measurement System. Work carried out included a literature review, development of load carriage measurement systems, design & validation of a load carriage simulator, evaluation of pack-based load carriage systems & sub-systems, and development of test protocols. The objective of phase IV, the IPCE project, was to improve measurement components and to develop a further understanding of specific factors that affect load carriage ability. Topics covered in this phase include development of a biomechanical model for load carriage assessment, parametric analysis of advanced load carriage systems, and analysis of human responses to load location in a backpack.
