Stress finite element models for determining the frequencies of free oscillations [PDF]
Инженерно-строительный журнал, 2016 Development of calculation methods, allowing determining the lower limits frequencies of free oscillations is actual. Such methods, in combination with the decisions by the method of finite element in displacements, will let to assess the accuracy of the

Журнал Белорусского государственного университета: Математика, информатика, 2019 Pathological changes in the oscillating system of the middle ear can lead to a decrease of the susceptibility threshold of the auditory analyser to sound vibrations and, consequently, to partial or complete hearing loss. Cartilage implants are most often

Chiral oscillations in the non-relativistic regime
European Physical Journal C: Particles and Fields, 2021 Massive Dirac particles are a superposition of left and right chiral components. Since chirality is not a conserved quantity, the free Dirac Hamiltonian evolution induces chiral quantum oscillations, a phenomenon related to the Zitterbewegung, the ...

Physical modeling of the rock bolt interaction with the rock massif [PDF]
E3S Web of Conferences, 2019 The results of the physical modeling of the “rock bolt – rock massif” system are presented. The characteristics of rock bolt free oscillations depending on the degree of its clamping and tension were studied on special test benches.

FREE VERTICAL OSCILLATIONS IN ROWING
Mechanika, 2011 The influence of the factor of vertical oscillation of academic boats on rowing effectiveness parameters defined as the change in the area of wetted surface of the boat caused due to the mean its draught increment is analysed in the paper. The indicators of rowing effectiveness conditioned by the factor of free oscillation of the boat are calculated ...

A study of the free oscillations of the Earth
Journal of Geophysical Research, 1961 Published observations on the toroidal oscillations of the earth are critically reviewed. A supplementary analysis of the record obtained by the Lamont strain seismometer is presented. Eleven toroidal modes are identified, and it is concluded that the periods are known to within 1 per cent.

Comprehensive analysis of the mechanical system system “fixture – workpiece” [PDF]
Журнал інженерних наук, 2017 Present work is devoted to locating and clamping of prismatic parts in fixtures during the machining on drilling-milling-boring machines. The special feature of locating schemes of parts of the present type is that one of the flat surfaces is used as a ...
