论文摘要
本文介绍了压缩预弯曲光束的机械双重机制。提出了一个管理方程，可用于预测和解释压缩预弯曲的光束的双重性。进行FE模拟和实验测试以验证分析解决方案。展示了光束独特的可调和不对称势能环境，这使压缩的预弯曲的光束可以切换其稳定位置，而无需将外力施加到它。基于此，将耦合的光束元件设计并用作构建块，以开发可重编程的元图，可以编程以展示不同的配置。
This paper presents a mechanically bistable mechanism of the compressed pre-curved beam. A governing equation is proposed which can be used to predict and explain the bistability of the compressed pre-curved beam. FE simulations and experimental tests are performed to validate the analytical solution. The beams unique tunable and asymmetrical potential energy landscape is demonstrated which enables the compressed pre-curved beam to switch its stable position without the need of applying an external force to it. Based on that, a coupled beam element is designed and used as a building block to develop reprogrammable metasurfaces that can be programmed to exhibit different configurations.
