分支双摆中反相模态能量转移的实验检测
Experimental detection of energy transfer into the antiphase mode in a branched double pendulum
AI总结：
本文提出分支多摆作为研究模态间能量转移的平台，反相模态局限于子连杆，便于制备初始条件，并推导出能量转移表达式，经实验数据验证。
AI中文摘要：
提出将具有分支的多摆作为研究不同模态间能量转移的便捷平台。反相振荡模态局限于“子”连杆上，这使得在不激发反相模态的情况下制备初始条件变得容易。理论上推导出能量转移的可处理表达式，并用实验数据进行了评估。
英文摘要：
Multiple pendulum with branching is proposed as a convenient platform to study energy transfer between different modes. The antiphase oscillation mode is localized to the "child" links, which makes it easy to prepare initial conditions without exciting the antiphase mode. A manageable expression for the energy transfer is derived theoretically and evaluated with experimental data.
