WebDec 1, 2024 · Measured vibration levels and frequency analysis were dangerous at 1× due to resonance problem. Finite Element Analysis was used to model the motor structure in order to find its natural frequencies and mode shapes. The results confirm that the third natural frequency is very close to 1× operating speed with deviation about 1%. WebFeb 1, 2024 · The finite element analysis was one of the most critical developments in applied mechanics , and FEM replaces the governing differential equations of distributed-mass system with a system of linear equations; this also shows how the FEM simplified the calculation of natural-vibration frequency.

WebFinite Element Analysis. When finding the modes of vibration of a structure, having computer modeling and analysis as a tool is extremely helpful. ... Thus, I perform an implicit dynamic analysis and analyze the virtual data to find that the frequency of natural mode of vibration is around 10.3 Hz. Unlike the eigenfrequency method, however, the ... The goal of modal analysis in structural mechanics is to determine the natural mode shapes and frequencies of an object or structure during free vibration. It is common to use the finite element method (FEM) to perform this analysis because, like other calculations using the FEM, the object being analyzed can have arbitrary shape and the results of the calculations are acceptable. The types of equations which arise from modal analysis are those seen in eigensystems. The physic…
