Japanese traditional bow, so called ‘Wakyu’, has been made from a bamboo. On the other hand, a bow which is made from new material as a glass fiber or a carbon fiber has been developed from 1970’s. These new material bow are easy to handle and are durable. However the vibration of a new material bow is different from that of a traditional bamboo bow at shooting an arrow. Therefore it is expected to develop a new material bow which has similar to bamboo bow in vibration characteristics.The purposes of this study are to measure the vibration characteristics of bows by using accelerometer and to make clear the effect of material and structure to the vibration characteristics. For these purposes, an experimental setup to investigate some of vibration characteristics of bow was constructed.In this paper, it is explained that the developed experimental setup and the basically vibration characteristics of a new material bow at shooting an arrow.
