  • Impact test of wood baseball bats made of Sugar maple, White ash, Yellow birch, Aodamo, and Dakekanba with fast pitched balls

説明

<p>Dakekanba is the most popular broad leaf tree in Hokkaido. The amount of resource in Hokkaido may be enough for replacing a part of the mass production of bats with Sugar maple, White ash, and Aodamo, which have been used so far in the world. Yellow birch of North America is the same attribute with Dakekanba of Japan. Full baseball bats with the quality to be used in official games were prepared; those fulfilled the standard of the Baseball Federation of Japan. As the preliminary test at bat in baseball fields, present study conducted an experiment of impact with fast pitched ball up to 160 km/h by means of air gun. The apparatus of the Toyama Industrial research and development center of Nanto city was used. The result showed that the deflection, vibration, and damping properties of Dakekanba were close to those of Yellow birch, which were intermediate between those of Sugar maple and Aodamo.</p>
