This paper describes the design and development of an advanced instrumentation Moving Deformable Barrier (MDB) for use in research crash testing to address vehicle aggressitivity and compatability issues. The instrumented MDB design is an adaptation of the current Federal Motor Vehicle Safety Standard (FMVSS No. 214) MDB design and duplicates as closely as possible its physical and dynamic specifications. Forty-four equally spaced low weight triaxial load cells are placed behind the main body of the aluminum honeycomb structure. In addition, an equal number of string potentiometers are placed in the rear of the cart to measure the honeycomb crush. The triaxial load cells were specially designed to measure forces in both the longitudinal and shear directions. During the initial design stage, the number of load cells, their weight, placement, type, durability and measuring capacity were considered.
