Abstract: To establish a recurve bow response online measurement system and to conduct both the static and dynamic measurement of load-related parameters of the bow system (including bowstring) so as to provide reference data for upgrading archery training level. Methods: A self-made carbon steel testing bench having the total length of the emitter and the bow at full draw, was used for both the static and dynamic test of the recurve bow used by the national archery team players and for the test of two archers’ arrow shooting. Conclusion: In the static test, both the relationship between the static strain response of the measuring point on the bow blades and the load transmitted onto the bow blades via the string, and the relationship between the pulling force and the pulled distance were linear; In the dynamic test, the strain response frequency of the bow limb without bowstring was 46.88Hz. When the bow blades were installed with the bowstring, all the strain response frequencies were 13.67Hz. When the shock absorber was installed, the bow limb had smoother response waves. In terms of effect, the single shock absorber had a better damping effect when installed on the upper part of the bow grip than when installed on the lower part. The combined shock absorber had a better effect than the single shock absorber; As compared with thick arrows, thin arrows are more suitable for the recurve bow system. The tighter the screws were fastened, the better overall performance the bow system had. However, the screws’ tightness had no effect on the intrinsic frequency of the recurve bow system of the type. The two archers had different dynamic responses when they used the same bow and arrows. Therefore, the purpose of archer training is to make his energy focused on the arrow’s flying direction.
