Numerical modal analysis – Christmas simulation 2021
Natural frequencies and modes from the gingerbread man Pfeffi
For this year’s Christmas simulation, we carried out a numerical modal analysis with the FEM freeware Salome Meca. Today I would like to introduce you to Pfeffi . Pfeffi is a gingerbread man, is approx. 400 mm tall and is made of aluminum (E = 70,000N / mm²). For our Christmas simulation we were able to persuade Pfeffi to undergo a numerical modal analysis. Additional dimensions in his arms and legs inspire Pfeffi to adopt the following eigenmodes: (more…)
