中文摘要:
      为了避免在传送过程中传送带与精密元件之间的摩擦损伤,设计了一种紧凑型非接触超声传送平台,对其可行性进行理论研究和实验验证。通过ANSYS动力学分析建立对称模型,模拟传送平台的模态和传送平台中心点的谐响应振型,结果显示,不同波数条件传送平台呈现出纯弯曲或混合波驱动状态。对所设计的紧凑型传送平台原型进行扫频实验,验证了超声传送过程的可行性以及悬浮频带和振型。理论及实验结果表明,根据不同使用条件,需要对驱动平台进行模态及承载能力的优化设计。研究成果可为超声悬浮平台模态振型和带宽的设计提供参考。
英文摘要:
      In order to avoid friction and scratching between the conveyor and the precision components when conveying object, an compact non-contact acoustic levitation prototype is designed, and the feasibility is theoretically and experimentally verified. The symmetry model is established through kinetic analysis with ANSYS. The modal and the coupled field computation at the central point of the transfer platform are simulated. The simulation results show that pure flexural or mixed flexural wave shapes appear with different wave numbers on the platform. Sweep frequency test is conducted on the compact platform prototype. The levitation experimental results confirm the feasibility of the ultrasound transfer process, the levitation frequency range and the mode of vibration. The theoretical and experimental results show that the optimal design of the modal and the carrying capacity of the driving platform is necessary according to different conditions. The research results provide a reference for the design of the mode and bandwidth of the ultrasonic levitation platform.
