[duvernost_udaju_id] => S
[popis] => The safety frame is the main element of passive safety for most racing cars. Till now the frames stiffness is investigated only on the basis of static loading tests, which are not able to take into account the dynamic effect of the high speed impact due to the car collision. For more correct frame safety analysis the dynamic impact loading simulation is necessary. The influence of the impact velocity on the frame stiffness, stress and deformation has been studied and comparison with results obtained for the static loading has been performed. The static and dynamic loadings exhibit very different stiffness, deformation and stress time courses in the time just after impact. Later the differences are not so big. Furthermore the car rollover has been modeled as a dynamic impact problem for the impact velocity 20 km/hour. A relative good agreement with corresponding prescribed static test has been achieved with exception of the time period close to impact. The explicit version of the finite element method (FEM) has been utilized for the impact computational analysis, namely FEM code LS-DYNA.

[nazev] => The influence of the first non-singular stress terms on crack initiation direction in an orthotropic bi-material plate
[nazev_orig] => The influence of the first non-singular stress terms on crack initiation direction in an orthotropic bi-material plate
[duvernost_udaju_id] => S
[popis] => A bi-material plate composed of two orthotropic parts leads to free edge stress singularity. This is considered as a bi-material notch with w1=w2=90degree under general loading. Besides the singular term the first non-singular term is also included in the stress distribution at the notch tip. The Stroh–Eshelby–Lekhnitskii formalism for plane elasticity is used to express stress and displacement fields and the strain energy density factor. The exponents of the singular and non-singular stress terms and corresponding eigenvectors are the solution of the eigenvalue problem resulting from the prescribed boundary and compatibility conditions at the notch tip. The potential direction of crack initiation is determined from the local minimum of the mean value of the strain energy density factor in both materials. The necessary knowledge of the generalized stress intensity factor and generalized T-stress is realized by means of the employment of the two state conservation integrals. Following the assumption of the same mechanism of rupture in the case of a crack and a notch, an expression for the critical values of the generalized stress intensity factor is obtained.

[popis] => A bi-material notch or a crack terminating at the bi-material interface composed of two orthotropic materials is considered. The stress and displacement fields are expressed using the Lekhnitskii-Eshelby-Stroh formalism for plane elasticity and as the result of an application of the psi-integral method. Knowledge of the basic stress concentrator characteristics such as stress singularity exponent and corresponding regular and auxiliary eigenvectors allows the psi-integral method allows one to evaluate the generalized stress intensity factor of the studied stress concentrator. The achieved results are used for the next analysis such as assessment of the potential direction of the crack initiation and for notch stability criteria assessment as an extension of standard crack fracture mechanics.

[popis] => The strength of glass or ceramic containing materials can be affected by the environment (stress corrosion). Under applied stress, crack-like defects may grow (sub-critically) for stress intensity factors, KI, below the fracture toughness of the material, KIc. The aim of the present work was to develop a two-dimensional finite element model to analyze the subcritical crack growth behavior of ceramic-based particulate composites. The maximum tangential stress criterion (MTS) was used to predict the direction of the crack propagation, in the framework of linear elastic fracture mechanics. The modeled material was a Low Temperature Co-fired Ceramic (LTCC), containing alumina particles embedded in a glass matrix. The experimentally determined SCCG material behavior (i.e. v-KI data) was implemented in the numerical model. The effect of the elastic modulus of the particles on the subcritical crack propagation was investigated. The conclusions of this paper can contribute to a better understanding of the subcritical propagation of cracks in particulate composites.

It is shown that the additional external loading can significantly influence residual lifetime of the pressured pipe. In this study the effect of the pipe geometry is considered. The shape of the propagating crack is estimated based on a special algorithm and the stress intensity factor is evaluated by direct method. The relation between crack size and a geometric function Y(a-s) for specific material and geometrical properties is found. The results of this paper should contribute to better understanding of the real pipe behavior and to prevent unexpected failure of the pressured pipe system due to non-homogenous distribution of the soil load.

[popis_en] => This article describes the shift of the subsynchronous frequency due to change in lubricant temperature. A small diesel turbocharger
for a passenger vehicle with semi-floating bearing system was investigated. Measurements were taken on a combustion engine
using an external device as a source of lubricant for the turbocharger. Two temperature regimes were selected, 30 degrees C representing
cold lubricant conditions, and 100 degrees C as the normal operating temperature. Lubricant pressure level was maintained at 1 bar during
the entire test procedure. Results show the significant influence of lubricant temperature on the subsynchronous frequency of rotors.

[popis] => The presented paper gives an overview of basic principles and recent trends in power management electronics for thermoelectric energy harvesting. Energy harvesting systems are a modern way how to feed the autonomous devices on-site using ambient energy. The ambient energy in the case of thermoelectric generators is represented by temperature gradients. Different temperatures are applied to the hot and cold sides of thermoelectric module which generates the thermoelectric voltage on its terminals. This effect is called the Seebeck Effect. Thermoelectric generators have recently been found as a promising way for powering the autonomous sensors. This application is particularly promising utilizing a higher integration by the MEMS or NEMS technology. Power management electronics is an essential part of any energy harvesting system. It utilizes a connection between the energy harvester and powered application. The main tasks for power management electronics also include the maximum power point tracking (MPPT), power conditioning, interconnection with accumulator and self-diagnostics. The presented paper shows the general requirements, principles and system-level considerations in the design and development of power management electronics for the thermoelectric generator. The presented principles are subsequently applied on the real case study.

[popis] => This chapter deals with a simulation modelling of the complex energy-harvesting unit based on MEMS thermoelectric generator. This chapter is mainly focused into the first steps in a development process analysis of demands given on the aircraft-specific thermoelectric harvesting unit, choice of energy storage elements, conceptual architecture of power electronics and simulation of various operating states based on the typical operating envelope. The whole simulation modelling process is implemented in MATLAB/Simulink Simscape. Commercially available thermoelectric modules produced by Nextreme Thermal Solutions, Inc. are used as the sources of energy. The raw power output coming out of each of these modules is in the range of tens of milliwatts. Special attention is paid to the choice of energy storage unit. Designs using supercapacitors and batteries as the electric energy storage elements are considered and evaluated. Several architectures of electronics are examined through the simulation modelling. The presented model represents an important step in the process of a mechatronic design of the complex aircraft-specific thermoelectric energy-harvesting unit.

[nazev_en] => Simulation of Power Management Electronics and Energy Storage Unit for MEMS Thermoelectric Generator
[popis_en] => This chapter deals with a simulation modelling of the complex energy-harvesting unit based on MEMS thermoelectric generator. This chapter is mainly focused into the first steps in a development process analysis of demands given on the aircraft-specific thermoelectric harvesting unit, choice of energy storage elements, conceptual architecture of power electronics and simulation of various operating states based on the typical operating envelope. The whole simulation modelling process is implemented in MATLAB/Simulink Simscape. Commercially available thermoelectric modules produced by Nextreme Thermal Solutions, Inc. are used as the sources of energy. The raw power output coming out of each of these modules is in the range of tens of milliwatts. Special attention is paid to the choice of energy storage unit. Designs using supercapacitors and batteries as the electric energy storage elements are considered and evaluated. Several architectures of electronics are examined through the simulation modelling. The presented model represents an important step in the process of a mechatronic design of the complex aircraft-specific thermoelectric energy-harvesting unit.

[popis] => This paper presents a novel approach to the design of a motorized rehabilitation device – active elbow orthosis (AEO) – inspired by the principles of robotic exoskeletons. The device is currently designed for the elbow joint, but can be easily modified for other joints as well. AEO determines the motion activity of the patient using a strain gauge and utilizes this measurement to control the actuator that drives the forearm part of the orthosis. Patient activity level is related to a free arm measurement obtained via a calibration procedure prior to the exercise. A high-level control module offers several types of exercises mimicking the physiotherapist. The device was successfully verified by tests on a number of patients, resulting in extended range of elbow-joint motion.

[duvernost_udaju_id] => S
[popis] => This paper presents a methodology suitable for estimation of residual lifetime of polymer pipes. The linear and non-linear distribution of residual stresses in the pipe wall is studied using FEM analysis. The approximate relation for the stress intensity factor calculation is presented. It is shown that the presented relation gives a stress intensity factor similar to the FEM analysis for the linear or non-linear distribution of residual stress. The suggested procedure produces a slightly conservative lifetime estimation where the accuracy of the procedure increases with increasing ratio between applied internal pressure level to residual stress level. The accuracy of the residual stress estimation and corresponding stress intensity factor is discussed and a final recommendation for lifetime determination based on simplified methodology is given.
