Mathematical modelling of friction-vibration interactions of nuclear fuel rods

Nuclear fuel rods (FRs) are transverselly linked to each other by three spacer grid cells at several vertical levels inside a fuel assembly (FA). Vibration of FA components, caused by the motion of FA support plates in the reactor core, generates variable contact forces betwee...

Vibration modes of a single plate with general boundary conditions

This paper deals with free flexural vibration modes and natural frequencies of a thin plate with general boundary conditions — a simply supported plate connected to its surroundings with torsional springs. Vibration modes were derived on the basis of the Rajalingham, Bhat and Xistr...

Using Fourier and Taylor series expansion in semi-analytical deformation analysis of thick-walled isotropic and wound composite structures

Thick-walled tubes made from isotropic and anisotropic materials are subjected to an internal pressure while the semi-analytical method is employed to investigate their elastic deformations. The contribution and novelty of this method is that it works universally for different loads, different&#x...

Usage of the particle swarm optimization in problems of mechanics

This paper deals with the optimization method called particle swarm optimization and its usage in mechanics. Basic versions of the method is introduced and several improvements and modifications are applied for better convergence of the algorithms. The performance of the optimization algorit...

Design of the blisk of an aircraft turbojet engine and verification of its resonance free operation

Integral turbine wheels belong to one of the most stressed parts of jet aircraft engines. In addition to high rotational speeds and temperatures, they are also subjected to dynamic forces from a non-uniform pressure field in the flow path. Dynamic forces even at a ...
