Abstract
Seven different stick models of varying construction and price were used in this study. Higher priced sticks had higher natural frequencies for the first and second bending modes due to lower MOI. Six shooters were utilized in an on-ice field study where the average slap shot puck speeds varied by as much as 17 mph from player to player. Puck speeds increased with increasing blade linear velocity after puck impact but incoming velocity had no effect on performance. This indicates shooter technique from ice contact to puck release was of most importance for higher shot efficiency. Wrist shot speeds increased with increasing stick stiffness, shaft deflection and decreasing MOI. The complexity of the slap shot motion led to stick properties being relatively unimportant while the simplicity and consistency of the wrist shot motion led to stick properties effecting shots speeds. A finite element model was employed to simulate the slap shot for field study validation and for observation of the effects of changing swing kinematics. The stick was modeled as a linear elastic material and the puck was modeled as a viscoelastic material. Puck speeds were found to increase only slightly with increasing shaft stiffness over a range much larger than that used in the field study. Similar to what was found experimentally, stick MOI had no effect on puck speeds and impacting the puck closer to the toe resulted in higher shot speeds. Model shot consistency led to a greater dependence on shaft loading when compared to experimental results.
