Oh, like this: https://www.google.com/url?sa=t&rct.../8/4/645/pdf&usg=AOvVaw2DBGVt6_5h1-fJ0Yv-EqoIKajan thana said:
So the "Predicted" graph was likely plotted using FEA tools, and the "Measured" graph was plotted directly from the acquired data. Presumably they were exciting the MEMS arm with a high mechanical impedance source and sweeping the frequency of that source to get the plot. Similar to how you plot the transfer function of a 2-port network...Kajan thana said:
Vibrational modes refer to the different ways in which a molecule or object can vibrate. These vibrations can affect the motion of the molecule or object by changing its shape, orientation, or position.
Vibrational modes play a crucial role in determining the physical and chemical properties of materials. For example, the strength and stiffness of a material are influenced by the types and frequencies of its vibrational modes.
The number of vibrational modes in a molecule depends on its molecular structure and the number of atoms present. Generally, a molecule with N atoms will have 3N-6 vibrational modes, where 3N represents the total degrees of freedom and 6 represents the number of rigid-body translations and rotations.
Vibrational modes can be studied and analyzed using techniques such as infrared spectroscopy and Raman spectroscopy. These methods involve shining light of specific wavelengths onto a sample and measuring the absorption or scattering of the light, which provides information about the vibrational modes present in the sample.
Yes, vibrational modes can be controlled and manipulated using different techniques such as laser excitation and mechanical stimulation. This can lead to changes in the properties of materials, which has potential applications in fields such as materials science and nanotechnology.
