| Abstract: | Models were developed for calculating the mechanical characteristics and the on-snow performance of snowboards.The snowboards
are constructed of layers of materials which may include wood, foam, honeycomb, fibre-reinforced composites and polymeric
materials.The models pertaining to the mechanical characteristics provide the bending and torsional stiffnesses, the flex
and the twist.A computer code (Snowboard-MECH) was written which yields numerical values for these characteristics.The model
for on-snow performance simulates the travel of a snowboarder of given height, weight and skill level, down an S-shaped course.A
second computer code (Snowboard-TURN) was written in support of this model; this calculates the time it takes the snowboarder
to complete the course.The two computer codes were verified by comparing their outputs with laboratory data and with data
generated by a snowboarder completing a prescribed S-shaped course.The results generated by the models and the data are in
agreement, lending support to the models and the corresponding computer codes.A procedure is described by which the computer
codes developed in this study can be utilized in the design of snowboards. |
