dc.description.abstractBionic solution for reinforcement of “travelling column” machine is developed. It concerns special project of old heavy precise machine redesign and renovation. It is proposed to attach tree-like polymer-concrete outer bandage to the flexible column. Bionic-shape vertical console is created. Design is proved by FEA simulation. Static rigidity is increased twice. Bending eigenmode frequencies rises from 14–18 Hz range to the 26–31 Hz one. Torsional resonance shifts frequency from 35.2 to 52.9 Hz. Resonance amplitudes are weakened in 1.88–2.76 times. Bionic bandage is recommended for static so dynamic conditions. It takes only 28 % growth of the weight.ru
