开发了用于计算滑雪板的机械特性和雪上性能的模型。滑雪板由多层材料构成，其中可能包括木材、泡沫、蜂窝、纤维增强复合材料和聚合材料。与机械特性相关的模型提供了弯曲和扭转刚度、弯曲和扭曲。编写了计算机代码 (Snowboard-MECH)，可产生这些特性的数值。雪上性能模型模拟了滑雪板的行驶。给定身高、体重和技能水平的滑雪者沿着 S 形路线滑行。编写了第二个计算机代码（Snowboard-TURN）来支持该模型；这计算了滑雪者完成路线所需的时间。通过将其输出与实验室数据以及滑雪者完成规定的 S 形路线所生成的数据进行比较，对这两个计算机代码进行了验证。模型和数据生成的结果一致，为模型和相应的计算机代码提供了支持。描述了本研究中开发的计算机代码可用于滑雪板设计的程序。
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.
