We describe a transducer system and analysis strategy that allows the determination of dynamic forces and moments applied by an arm-swinging animal during locomotion. We have employed readily available technology and analysis procedures to produce a low-cost but effective system. The solutions to several problems in the design of the system are provided, and the functional characteristics of the system are demonstrated using both an inert pendulum and an actively brachiating gibbon (Hylobates lar).
我们描述了一种换能器系统和分析策略，该系统能够测定动物在运动过程中摆臂时所施加的动态力和力矩。我们采用了现成的技术和分析程序来构建一个低成本但有效的系统。文中提供了该系统设计中几个问题的解决方案，并使用惰性摆和主动臂行的长臂猿（白掌长臂猿）展示了系统的功能特性。
