This thesis describes an approach to the analytical solution of the periodical vibrations of mechanical systems with any number of degrees of freedom with periodically time varying parameters (mass, damping, stiffness matrices and excitation vector). The model is described by a differential-...

The main aim of this work is to design a new roofing system on the bus terminal at the central bus station in Pilsen. First, the present roofing is evaluated and the imperfections are detected. The main load cases which act both the present and the new designed&...

The diploma thesis begins with description of surfaces of screw rotor. Next part deals with determination of force effects acting at rotors of screw compressor. This knowledge is further used for computing of deformation of screw compressor's housing and bearings. Algorithm used for...

This work deals with basics of mathematical modelling of turbulent flows. We consider model of compressible viscid fluid described by the system of Navier-Stokes equations, from which the system of Favre averaged Navier-Stokes equations is derived. The system is closed by turbulence&#x...

This thesis is concerned with a mathematical modelling method for rotating continuum with asymmetry of cross section. For calculation of characteristics of a general cross section the Matlab algorithm is created. Finite element method is used for modelling of rotors with a general ...

This work deals with the description of mechanical properties of rubber that is used as a vibration-damping element in tram wheels. Tests in uniaxial tension, compression and simple shear have been made. The material model that was chosen consists of Mooney-Rivlin five-parameters materi...

This work deals with the strength analysis of a laminated composite plate which is joined to a construction using a pin. Experimental specimens made of a carbon fibre composite plate were tested. A special experimental device was designed and produced. This device is possible ...
