Web14 mrt. 2024 · The mode shape is shown by the displacement result. The displacements are not random. If they were random, the mode shape would not appear to be smooth. It would be random. The maximum magnitude is scaled to some value. (Perhaps this is what you meant by random.) So why modal frequencies have dependence on the mesh size? WebModal analysis is a method to describe a vibrating structure in terms of its natural characteristics which are the frequency, damping and mode shapes – its dynamic properties. A standard setup for experimental modal testing requires sensor technology (force transducers, accelerometers, cameras or non-contact laser vibrometers), data ...
