About General Purpose Dummies:

General Purpose dummies are a low cost alternative to the various dynamic crash test dummies.  They may be used for ballast dummies as well as testing harnesses, flotation devices and similar protection gear.

Why we test with General Purpose Dummies

General purpose dummies allow the testing of fall protection harnesses and flotation devices. They are also used for training emergency response personnel in techniques of carrying people in need of rescuing on flat surfaces as well as down telephone poles and in other difficult situations. Their exterior surfaces are hard but compliant foam for an approximate human feel. They may be made buoyant for testing in water, and they may have minimal transducers and data acquisition systems mounted in them, and made waterproof. They provide a dummy for use where adherence to federally mandated dynamic performance criteria is not necessary.

History of the General Purpose Dummies

The dummies were developed in the U.K. in the 1990’s.

General Purpose dummies in the US Code of Federal Regulations

These dummies are not in the Federal Code.

Future General Purpose Dummies

Modified versions of these dummies may be made to respond to specific customer requirements.

General Purpose Dummy Review

These dummies expand the role of the anthropomorphic test device into many areas beyond vehicle crash testing. Since dynamic performance testing is not necessary the dummies may be produced economically.

Design Criteria

  • 50th Percentile male dimensions
  • Limb, hip, spine and neck articulation similar to the human body
  • Overall weight range of 56 - 100Kgs. (123 - 220 pounds)
  • Simple to use with minimal maintenance

Articulation

  • The neck can move through an arc of at least 60° both forward and rearward.
  • The arms swivel about the shoulder pivot 30° from the vertical to a position 180° forward from the vertical. At any point on this arc they are able to swing out from the body by at least 90°. The range of movement at the elbow is a minimum of 120° from the straight position.
  • The knees lock when the lower leg is angled back at 120°.
  • The spine articulates at the lumbar and mid-thoracic points. 

Durability

The dummy is skinned in a durable PVC material. A service life of several years can be expected. 

Buoyant Version

(For ’Man-Overboard’ Rescue Training)  This is similar to the “dry” use dummy but incorporates closed cell foam mouldings within the major body components in order to give some degree of buoyancy. A life jacket or buoyancy aid should also be fitted if the dummy is to be used for sea rescue training. Also available with a stainless steel skeleton. 

Maintanence 

The standard dummies are constructed with steel skeletal components that are zinc plated to BS 3382 and fastenings are either zinc plated or stainless steel. Maintenance is minimal. It is important to grease all moving parts regularly and to check nuts and bolts are secure. Particular attention should be paid to the lifting eyebolt in the head.
