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...
The regularities of changes in the frequencies and forms of natural oscillations and the stress state of a silicon sensing element of a mechanical MEMS accelerometer system depending on changes in the radii of rounding of structural elements are considered. An increase in the natural frequencies of the system and stresses in torsion suspensions has...
This presentation is an addition to the article Dounar S.S., Ausiyevich A.M., Lapuka A.D., Shvedova D.N., Rodenia A.V. FEA stress analysis of the Tower of Pisa as a way for students to explore the sphere of virtual testing. «System analysis and applied information science». 2022;(2):67-75. (In Russ.) (https://doi.org/10.21122/2309-4923-2022-2-67-75...
FEM simulation of Eddystone lighthouse is provided. That construction is a case of legacy load-bearing system (LLBS). Incorporated tree-like granite tower is modelled as well as cylindrical basis above rock. Load cases including gravity force, wind thrust, water stream and 50-year wave impulse are investigated. Static, modal and transient FEA are a...
The paper describes a method for condition monitoring of a complex mechanical system based on pre-computer FEM simulation of vibrations. The interrelation of vibrations of the connected elements of the system, described by transfer functions, is shown. The occurrence of resonant vibrations in directions orthogonal to the direction of the disturbing...
FEA of stress state for Pisa Tower is accomplished. Imaginary vertical orientation of the tower is simulated as well as its actual leaning position too. Moderate deformational incompatibility between “column drum” and “stem” load-bearing systems is revealed. Twofold overstressing of lower colonnade is found comparatively to the stem surface. Tower’...
