Synthesis of algorithms for diagnostics of electric circuits

Print

EMUs electrical circuits are divided into low-voltage control circuits, high voltage power and auxiliary circuits and in general constitute a complex, multi-element, multiply object with feedback loops and a large number of parameters, and its reliable operation has a significant influence upon the security and uninterrupted functioning of the railway carryover conveyor.

A repair system, designed to maintain an acceptable reliability level of rolling-stock and based on the scheduled preventive principle, has already exhausted its resource of cheap, skilled labor force and is not currently able to provide a high level of safety, keeping to schedule and improving the transportation process quality while reducing costs. Lack of modern and reliable devices for technical condition monitoring is the main reason of EMUs defects and failures. According to the statistical accounting of «Russian railways» JSC, about 60% of these defects and failures occur in electrical circuits.

Achievement of a high efficiency and reliability in the technical condition assessment of complex objects is possible on the basis of technical diagnostics devices, which development and implementation is preceded by phases of the object study and the diagnostic algorithms synthesis.

Electrical circuits can be represented as a single discrete logic device, whose input, internal and output signals have two stable states, respectively, and for their analysis it is advisable to use the mathematical apparatus of logical algebra.

Quality diagnostics of electric circuits assembling

Print

Serviceability and performance capacity of repaired equipment is not objectively a guarantee of its correct operation as a part of this or that electric multiple unit system. Relationship between the elements, devices and units can be broken as a result of installation defects, damage can appear while transportation, assembling and subsequent debugging. The defects appearance at this stage of the technological cycle leads not only to duration increase of EMU putting into operation (debugging period), but, in the case of a defect omission, to spoilage and failures on the line.

Improving the quality of the motor driven rolling stock with a simultaneous reducing of debugging duration and complexity is possible on the basis of automated systems for comprehensive diagnostics of repair and assembling quality of the most complex and critical EMUs systems that provide a reliable quantitative and qualitative assessment of their technical condition, in accordance with the guidelines requirements.

The article presents some results concerning development and application of systems for comprehensive diagnostics of EMUs repair and assembling quality. EMUs are widely used at enterprises of «Russian Railways» JSC and at factories which are prospective for the railway industry being a means of improving reliability, maximizing EMUs exploitation with a simultaneous reducing of costs for repairs and speedy reconstruction of repair system on safe resource-saving basis.

Benchtop system for rolling bearings acceptance vibration analysis

Print

Design life of rolling bearings is determined by bearing capacity rating, equivalent load and bearing type (ball or roller). The equivalent load is determined by two factors: static and dynamic.

If the static load is determined by the machine operation mode and can vary within wide limits, the dynamic load is determined by the bearing state - all the roughness and defects in rolling elements and surfaces lead to an increase in dynamic forces affecting the bearing, and as a result, reduce its life. Besides, this decrease in life can be rather significant. Thus, for bearings with spoilage in production, when static and dynamic forces are comparable, the design life drops to 8 times for ball bearings and 10 times for roller ones. This explains the necessity for carrying out rolling bearings input vibration analysis before they are installed on the repaired or re-manufactured machines.

The article shows a dependence diagram of the bearing velocity overall level from the magnitude of the applied radial static load. It has been concluded that when measuring the bearing vibration parameters, we can judge about the magnitude of dynamic forces affecting the bearing, and thus we can more accurately evaluate its potential life.

Solution to the problem of purchased bearings 100% acceptance testing is the application of vibration analysis methods, where through the analysis of vibration signal one can quickly give an opinion on the bearing state without disassembling and micromeasuring. To solve this problem the benchtop system COMPACS®-RPP has been developed.

There is quite a large scope of the piston machines (PM), where the safety of their operation is paramount and decisive factor. These are PM of petrochemical complex (PCC) potentially hazardous facilities.

Sudden and emergency PCC equipment breakdown threatens not only the appearance of significant economic losses due to downtimes and working capacity restoration, but also environmental and man-made accidents and disasters. In this regard, it is very important to obtain not only reliable, but early diagnosis as well, which can provide trouble-free operation with maximum resource use of the replaceable units and parts.

This can be achieved only by providing a diagnosis-making at a time-interval, shorter than the malfunction development. For the PCC equipment this period can lie in the range from several minutes to hours, days, weeks, months.

Orthogonality of vibroacceleration, vibrovelocity and vibrodisplacement signals in vibration analysis tasks

Print

Search and application for an estimation of a technical condition of machines of orthogonal diagnostic attributes represents rather actual problem as essentially increases reliability of diagnostics. Experience shows, that development of various malfunctions of rotor machines leads to that parameters vibroacceleration, vibrovelocity and vibrodisplacement react to these malfunctions on a miscellaneous. In a practice of vibration analysis and vibrocontrol the signals of vibroacceleration and vibrodisplacement often do not use, including their closely connected with a signal vibrovelocity, that these parameters are connected among themselves by differential-integrated ratio. These cases specify significant narrowing of a range of diagnosed malfunctions at use only one of these parameters.

By analytical researches, by numerical computer modelling and by means of natural experiments it is shown, that at diagnosing such malfunctions as defects of rolling and slidings bearings and, impellers of pumps, tooth gearings, infringement of centering of machines and fastening of units of machines to the bases, among themselves and to other attached designs, vibroacceleration, vibrovelocity and vibrodisplacement it is possible to consider parameters practically orthogonal. Thus, sharing for diagnostics of all three, parameters allows to observe in a spectrum of fluctuation of all frequencies raised in the mechanism.
