The Effect of Ankle Motion on Ski Binding Release Tests Using an Anthropometric Dummy

Source

A series of tests were conducted on an anthropometric dummy used for simulating skier impacts. The objective of the study was to determine the effect of the amount of ankle plantar-dorsiflexion motion on the moments experienced by the dummy skier at impact.

Two types of binding systems were used for these tests. One type was a classical ski boot-binding system. The second type of system used a unique, very soft boot that incorporates a binding mechanism. Boot bindings were set to release at approximately the same values. The dummy skier impacted a barrier to simulate a mogul impact. In other tests, the dummy skier impacted a pole simulating a slalom pole. One hundred tests were conducted at impact velocities of 19 km/h (12 miles per hour). The maximum moments acting on the dummy skiers tibia (distal third) were recorded.

It was concluded that a change in allowable ankle motion: 1. had more effect on the classical ski boot binding system than on the soft boot system and 2. had more effect on barrier tests (mogul tests) than on the pole tests.
