Fea study of effectiveness of bionic legacy-shape console as huge machine tool’s column

Concept of machine tool’s column in the appearance of vertical bionic console is proposed. Console was 3D-transformed from the shape of legacy oak-like structure – Eddystone lighthouse. It is proposed to create the variable-section column with “layer-by-layer” technics from the polymer concrete.

FEA shows high stiffness of the column. It increases from 1500 to 11000 N/μm from top to bottom along vertical guideways. Such stiffness needs only 19.3 ton of concrete for the instance of 4.5 m height’s column. FEMmodelling pointed out rather high eigenmode’s frequencies (˃49 Hz). FRF is appropriate for pre-resonance heavy cutting as for post-resonance finishing. Proposed bionic-shape column is perspective as for stand-alone variant so for portal composition created by two opposite columns.
