摘要
利用Tracker软件追踪和分析了有摆线弹簧摆的内共振现象,实时描绘了内共振的振动位移图、相图、轨迹图和能量图,实验表明起振角对径向振动能有较大影响,摆线可以取代部分等长弹簧实现内共振,拟合计算的径向和横向振动的固有频率与理论结果一致。
The spring pendulum with cycloid has been tracked and analyzed by the software Tracker, and the vibration displacement diagram, phase diagram, trajectory diagram and energy diagram of the internal resonance are depicted in real time.The experimental results show that the initial vibration angle has a great influence on the radial vibration energy, and the cycloid can replace some of the equal-length springs to achieve internal res- onance.The natural frequencies of radial and lateral vibrations calculated by fitting are in agreement with the theoretical results.
