项目摘要
RUI: Modal Testing Using Ultrasound Stimulated Radiation Force ExcitationAbstract:The goal of this faculty-student project is to investigate the capabilities of ultrasound stimulated radiation force excitation in air as a noncontact method of measuring vibrational modes. The unique characteristic of this method is that a driving force can be applied to the object through the interference of ultrasound signals, with no physical contact between the transducer and object. When ultrasound radiation force excitation is coupled with detection using a laser vibrometer, this provides the distinct advantage of both excitation and detection completely without contact. Since there is no mechanical contact required to vibrate the object, this technique has great potential in modal testing, especially in the study of Micro Electro-Mechanical Systems (MEMS) and similar small devices. Using the ultrasound radiation force, it is also possible to selectively excite different vibrational modes of an object while suppressing others. This project will result in a more fundamental understanding of the capabilities and limitations of the ultrasound radiation force, and its application for modal testing. In parallel to the detailed experimental studies, another major objective will be to create a computer model of this excitation process. This model will be essential for detailed quantitative studies of the response of some objects, to develop new techniques, and to study practical applications of the ultrasound radiation force excitation.
摘要:本项目的目的是研究空气中超声受激辐射力激励作为非接触测量振动模态的方法的能力。这种方法的独特之处在于,可以通过超声波信号的干扰对物体施加驱动力,而换能器与物体之间没有物理接触。当超声波辐射力激励与激光测振仪的检测相结合时,这就提供了完全不接触的激励和检测的明显优势。由于振动对象不需要机械接触,因此该技术在模态测试中具有很大的潜力,特别是在微机电系统(MEMS)和类似小型器件的研究中。利用超声波辐射力,还可以选择性地激发物体的不同振动模式,同时抑制其他振动模式。该项目将使人们对超声辐射力的能力和局限性及其在模态测试中的应用有更基本的了解。在进行详细的实验研究的同时,另一个主要目标将是建立这一激励过程的计算机模型。该模型对于研究某些物体的响应、开发新技术以及研究超声辐射力激励的实际应用具有重要意义。
