WebMar 14, 2024 · The frequency is also related to the mass distribution. Depending on how the mathematics are handled, smaller elements may give a better approximation of the mass distribution which changes the frequency. Why can't I just idealize this body with a single mass 'm' As implied by Solar Mike's comment, the body does not vibrate as a single … WebModal analysis can employ any type of geometry: •Solid bodies, surface bodies and line bodies. •The Point Mass feature can be used: –A point mass adds mass without additional flexibility to the structure thus reducing the natural frequency (K/M)^0.5. •Material properties: Young’s Modulus, Poisson’s Ratio, and Density are required.

Web2 days ago · Hi community, I have done a modal analysis of a container in which a fluid is considered as a point mass. This point mass is defined using free standing remote point. Free-free modal case is considered. After calculation for 20 modes, I find out that 6 modes are zero and additional 7th, 8th and 9th mode frequencies are almost zero. WebApr 13, 2024 · Detailed explanation of the modal expansion and selecting only certain modes for harmonic analysis is given in the attached document and the demo example provided.
