prototype has been developed allowing to undertake automatic analysis of stresses in different directions 1 INTRODUCTION To respond to the strongly expressed needs of several mechanical professions (bearings, gear systems, engines/compressors/turbine, thermal and surface treatment, etc ), CETIM
D Otte, Leuven- Measurement Systems, Leuven, Belgium ABSTRACT The project deals with structure-borne sound intensity(SAI) Three groups of technical problems were addressed which neededfirther development in order to enable the SAI approach be better exploited in practical applications: development of novel SAI measurement techniques,

analysis is made on level in which the smallest par ts are modules (subsystems) sil safety integrity level (iec 61508) system level analysis analysis is made on high level in which the smalles t parts are subsystems top-down method/analys is/ approach the analysis begins with top events and the initiat ing factors are concluded
microstructural changes using cyclic stress-strain curves analysis is no more possible, at least with conventional measurement systems, since the macroscopic behavior is quasi-elastic To cope with this problem, we propose to use the energy signature of the deformation mechanisms The temperature increase of the specimen will be

THE ADVANTAGES OF OIL ANALySIS SySTEMS: Oil analysis is a very effective method of early detection of machine damage Impurities reduce the average life of the machine and oil Chemical changes lead to loss of lubricity The metallic particles have a negative effect and accelerate the aging of the oil
