Abstract
The invention discloses a recurve bow response on-line detection system. Resistance strain testing, vibration testing and a control virtual-type signal analyzing soft and hardware technology are adopted; the static and dynamic strain and acceleration response of selected testing points on a recurve bow and mechanical dynamic parameters of the recurve bow are detected in real time on line, and objective experiment data are provided for the training of sportsmen and the development of a novel recurve bow. The particular implementation is that a small-type three-shaft resistance strain rosettes and a micro-piezoelectric-type acceleration transducer are bonded on the selected testing points of the recurve bow; response signals are transmitted to a strain meter and a vibration testing meter by leads; and after being converted and amplified, the response signals are transmitted to a control virtual-type signal analyzing meter for real-time analyzing treatment, thus the corresponding data curve diagrams and animation display and the like are obtained. The detection system can not influence the using performance of the recurve bow and the normal motion of users, not only can be used for the training of contestants, but also can be used for the detection analysis of stress and response of the recurve bow and prevents from adopting and installing each type of shock absorbers blindly, and is an effective means for archery coaches, sportsmen and the recurve bow researchers.
