Design is reliable in actual operational conditions ([[https://en.wikipedia.org/wiki/Boeing_CH-47_Chinook|link]]). Added constraints stiffen up the structure, thus increasing natural frequencies. However, a 0 Hz rigid body mode natural frequency may rise to a finite value due to added positioning constraints; the associate natural mode may be excited in resonance by dynamic loads. **Poor man dynamic response animated view** {{ :wikialtro2018:animacomp.proc | MSC.Mentat procedure for creating poor man harmonic response animations}} {{ :wikifemfuchde2019:animamodipropri.proc | MSC.Mentat procedure for creating poor man natural mode animations}} **Structural damping references** {{ :wikipaom2017:structural_damping_values_jdstevenson.pdf |}} {{ :wikipaom2017:damping_cross-reference_and_material_properties.pdf |}} {{ :wikipaom2017:f_orban_damping_of_materials_and_members_in_structures.pdf |}} {{ :wikipaom2017:tom_irvine_damping_in_bolted_and_welded_joints.pdf |}} {{ :wikipaom2017:estratto_afwal-tr-84-3089v2_dampingvalues.pdf |estratto}} vol. 2, sezione 8 di Soovere, J., and M.
