Opis:
Transform the way of visual indication of vehicle traction parameters and the introduction of instinctive, concentrated in one place on-board device service is now possible following the development of microprocessor systems. Centralize system for diagnosis and control of the vehicle in a single desktop, such as the one described here, brings except cost savings also facilitation in addition to the driver and service. Indicators of vehicle speed, engine rpm and other parameters of traction, and the rates and indication of operation states used for additional equipment during the performance of the activities are concentrated in one place. Controls elements, such as circuit breakers, switches and buttons are placed within the areas of appropriate comfort are grouped into blocks that are functionally similar, which further facilitates their location and service. The modern, multi-track switches allow additional control versatility, while reducing their volume, which facilitates access to each of them. Panel equipped with universal input and output circuits and system software provides the flexibility to work with the latest generation of sensors and actuators, and components used previously as well. This allows the design of modern devices and simple upgrading of vehicles already in service.

Opis:
The knowledge of the dynamic stat and structure of the system allows desercribing its behaviour, and allows creating prognosis models of the system behaviour in the function of dynamic evolution time, based on the model of the technical state symptoms growth. Most often, however, there are no known equations describing behaviours of the system in the function of dynamic evolution time, which accounts for the need to apply new tools to examine the dynamic state. There is, therefore, the requirement to experimentally verify analytical technical models as the proper one is a model which is verified in practice. An experiment is, therefore, often only an inspiration for further researches leading to the optimization of the construction. In this work presented are chosen problems of machines technical state diagnosis with the use of identification and technical diagnostics methods. Relations between methods of dynamic state evaluation and methods of technical state evaluation were indicated. Example modal analysis results illustrate the complexity of projecting dynamic state researches into diagnostic researches of machine state evaluation.

Opis:
Spiroid gear is one of the progressive varieties of intersecting axis gears. It has a number of advantages: increased overlap coefficient, favourable contact conditions. Spiroid gears are notable for high loading and overloading ability, increased smooth running and less sensitivity to manufacturing and assembly errors, high reliability and durability. The analysis of the results of experiment on research of vibration of the spiroid gear PS-124 has shown, that the vibration level at frequency 200-300 Hz is reduced on 5 dB at increase of the resistance moment up to 1000 Nm at clockwise rotation of the reducer and at increase of the resistance moment up to 800 Nm at counter-clockwise rotation of the reducer. The vibration level at frequency 700-800 Hz is also increased on 5 dB at increase of the resistance moment up to 1000 Nm at clockwise rotation of the reducer and at increase of the resistance moment up to 800 Nm. If these vibration levels are exceeded, a defect is likely to occur. Economic efficiency of application of diagnostics systems is caused by increase of reliability and quality, reduction of accidents, decrease in defects, reduction of idle time of expensive equipment, reduction of expenses for maintenance and repair.

Opis:
Laboratory tests are the cheapest and easily accessible source of medical information about a patient. Although they make an important and frequently decisive element of the diagnostic and therapeutic process, the expenditure on tests in Poland is many times lower than that in other countries of the European Union. The Supreme Audit Office, in accordance with its work plan and guided by the suggestions of the Parliamentary Health Committee, has conducted an audit to evaluate the organisation, quality, access to and financing of the activities related to laboratory diagnostics. The audit comprised: the Ministry of Health, medical entities and laboratory diagnostics subcontractors, including medical diagnostic laboratories in six regions of Poland.

In the present paper results of modelling of wind interaction with a water layer surface and research of the vortical structures arising downstream the flow around bodies are described. Results of the use of the method of acoustic diagnostics of spatially - periodic vortical flows are presented. At physical modelling in laboratory conditions wind was created with a low-velocity wind tunnel. The structure of an air stream and convective cells on water surface was investigated with the help of visualization. Some pictures of structures on the shallow sea surface are also demonstrated and discussed.

Opis:
Vibro-acoustic diagnostic methods which are used on marine high-speed diesel engines with turbochargers are presented in this paper. Vibration and acoustic signals generated by turbochargers need different signal processing methods to be effective and faultless in turbochargers diagnostics. Diagnostic methods which based on vibration and acoustic signals analysis are sensitive on engine load and speed changes. Methods presented in this paper based on vibration and acoustic signals processing in time and frequency domain. Using this methods checking technical condition of the turbochargers and its rotors and bearings without stopping the engine and dismantling it is possible. Examples of radial-flow rotor turbine overgrown by carbon soot and axial-flow rotor turbine without turbine blades, sound intensity level of turbocharger and acoustic spectrum of turbocharger in octave mode acoustic spectrum of turbocharger in octave mode for two different technical conditions, acoustic and vibration signal spectrum of the turbocharger, vibration acceleration amplitude of first harmonic for three turbochargers, values of harmonic vibrations of accelerations equivalent of turbine blades number, amplitude of vibrations accelerations in frequency domain for turbocharger in good and bad technical conditions are presented in the paper.
