复合弓 (现代弓) Compound bow(重定向自Compound bows)
![]() ![]() ![]() ![]() 复合弓是种利用滑轮省力及靠复合材料制作之弹簧板,支撑握把,弦线等组件所结合而成。而所用滑轮组成可分为两种:上下轮皆为凸轮,或是一个凸轮与一个圆惰轮所组成。复合弓的速度的单位为fps。 目前很多数厂商使用以复合材料制作的弹簧板,材质通常以玻璃纤维与碳纤维预浸环氧树脂布料成型,借由模具热压成形或纤维板加工成所需形状来达到所需目的。 弓身握把部分则分成碳纤维、镁合金、铝合金所制造。 镁合金目前则是采用压铸模具成形为最佳,但是后加工研磨须防止火花产生因为镁活性高又遇水易产生氢气造成气爆。 铝合金目前使用最广常用的可分成压铸成形与cnc电脑铣床加工成形,后者单价成本高,故又有厂商开发节省铝合金用料的铝挤型方式成形,例如美国专利PAT US05335644所用的方式。另一种方式则使用分成二段或三段式加工在借由定位销(PIN)与螺丝组装成形此种方式大多用在长度较长的握把上,使用此种方式的复合弓有美国ALPINE ARCHERY,MARTIN ARCHERY,LIMBSAVER ARCHERY,KODIAK ARCHERY等厂商。

Compound bow 复合弓 (现代弓)(重定向自Compound bows)
![]() ![]() ![]() ![]() A compound bow is a modern bow that uses a levering system, usually of cables and pulleys, to bend the limbs. The pulley/cam system grants the wielder a mechanical advantage, and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow. This rigidity makes the compound bow more energy-efficient than other bows, as less energy is dissipated in limb movement. The higher-rigidity, higher-technology construction also improves accuracy by reducing the bow's sensitivity to changes in temperature and humidity. |
