フライラインの力学（フライの影響）

抄録

Lure fishing and fly-fishing have been positioned as sports deliberately different from the traditional Japanese fishing-style. In the case of fly-fishing, casting is the element which anglers must master in order to cast a fly, done so by using the weight of a line. This study uses experimental and computational analysis to investigate the dynamic behavior of a fly line. Fly-fishing is constituted by various elements, but the importance that casting holds is extremely large. Fling speed, the casting process and the loop shape of the line while in flight are important that casting holds is extremely large. Fling speed, the casting process and the loop shape of the line while in flight are important for the proper presentation of flies. Moreover, the shape of a fly line is also important for a long cast or controlled cast. Fly is a lure that imitates an aquatic insect or a small fish, and becomes the prey of the target fish. And, there are countless of fly patterns. Therefore, anglers necessary to select an appropriate rod or line according to the size of the fly. In this paper, a rod, a line and arms are modeled by using rigid bodies and links. The time history behavior of the model is calculated by pseudo angler velocity of the arms. The validity of the model in detail is investigated. And, proper rod and line in accordance with the fly of the size is verified.
