Abstrakt: This contribution deals with the functional description and initial setting of the Reactor Vibration Monitoring System (RVMS) that is supplied as a part of the [...]
19.
The paper deals with the modelling of balancing machine vibration and the identification of the stiffness and damping coefficients of oil-film bearings. The real balancin [...]
20.
In this paper transfer of vibration from motor to the bottom group of rotary drier is analyzed in the ADAMS/Vibration module environment. Excitation from unbalanced motor [...]
21.
The paper deals with an application of drilling method in order to determine the residual stresses in big forgings for turbine rotors and railway axles. Residual stress w [...]

Puklický, L.
Steel-concrete composite columns are extensively used in modern buildings. Steel being of high tensile strength presents a high quality building material, concrete on the [...]
24.
Linseed oil was commonly used in ancient times as a protective treatment for building materials due to its ability to grant hydrophobic properties. It is an environmental [...]
25.
Since ancient times organic additives such as milk, curd, whey, blood, oils, fruit juices, etc. have been added to mortars. The majority of technological procedures were [...]
26.
The subject of the paper is the probabilistic safety assessment of an unbraced steel frame containing leaning columns and exposed to several variable loads. Reliability a [...]
27.
Changes of mechanical properties, namely of modulus of elasticity, often play a role of damage accumulation indicators in the framework of fatigue behaviour of composite [...]
28.
In this paper the authors propose a new procedure for the normalization of the free vibration mode shapes of a linear structure subject to seismic load. The normalization [...]
29.
Frequency modal and damping characteristics of an aeroelastic model designed for experiments in the wind tunnel are studied. Based on the experimental modal analysis the [...]
30.
Ductile fracture criteria are used for fracture prediction in metal forming processes. In this paper, there is briefly described the method of criteria verification and t [...]
31.
Hole drilling method is a total numerical simulation of tension or bending loading of two types of beam specimens. The FEM model of the special drilling strain gauge rose [...]
32.
This paper is concerned with mathematical modeling of the imperfect bladed disk with friction elements, which are used to suppress blade vibration. These kinds of systems [...]
33.
Vítek, K.
The idea of the presented numerical simulation technique corresponds to the E 837 standard concepts but is more universal. It transforms the strains, arising during the h [...]
34.
Naď, M.
The existence of a crack in a structural member introduces local modification of flexibility and consequently affects the dynamic behaviour of the cracked member. In this [...]
35.
Král, J.
A long-term measurement of the wind response of the first building started in 2007and of the second building in 2009. The response monitoring is automatic and continues. [...]
36.
Omishore, A.
The verification of the design reliability of a steel element according to the concepts of standards EUROCODE 3 and EN1990 is presented in the article. Reliability analys [...]
37.
The paper is focused on analysis of changes of eigenfrequencies due to local damage in beam buckling problem. The aim is determination of suitable initial parameters for [...]
38.
The application of the drilling test on the characterisation of homogeneous stones is widely used, mainly on carbonate stones that are softer. The drilling revolution and [...]
39.
The paper is focused on damage identification of dynamically loaded structures using methods of soft computing including artificial intelligence. The damage and variabili [...]
40.
The endeavour to use the changes of dynamic characteristics for the determination of damage or other imperfections of structures is not new. The rudimentary application o [...]
