WebThe participation factors are calculated from the product of the mode shape, the mass matrix and a vector of ones. For mode i the participation factor is calculated as: … WebModal participation factors The participation factor for mode α α in direction i, Γαi Γ α i, is a variable that indicates how strongly motion in the global x -, y - or z -direction or rotation about one of these axes (indicated by i, i = 1, 2, …, 6) is represented in the eigenvector of that mode. It is defined as

Webmodal mass participation factor, in practice modes with negligible modal effective mass are removed from the equations of motion, since its participation to the overall response is small [20,38]. However other definitions have been proposed, for instance, Wilson [25] used a mode participation factor similar to (8) to WebIn this context, modal analysis based on different modelization techniques, i.e., considering both an all-atom (AA) and coarse-grained (CG ... are displayed. In this case, the hydrogen atoms are disregarded due to their low mass participation. The largest longitudinal dimension of lysozyme is also shown in the figure, which corresponds to 46 Å ...
