The article presents the results of research in improving the reliability of the vibration-based diagnostics test results of industrial equipment. It is possible to achieve such results through the modernization of the expert system by applying the theory of identification measurement signals. It is proposed the conversion of vibration signals into the table clusters of standard names with known distribution laws. The technique of intelligent processing of vibration signals and measurable technology to create a special database connection clusters of quantitative and qualitative evaluation of a diagnostic condition of the equipment are considered in the article.

The article offers an approach for training of students from qualification degree ‘Master’ in the specialty of ‘Industrial engineering’. It represents analyses of suitable expert systems which are used throughout the process of computer-based designing and diagnostics of mechanical products. We have created a scheme of an expert system for gear transmission designing as well as algorithms based on rules of production for the purpose of investigation of stress concentrators and change of the geometry of segments from a gear or a shaft. We have also rationalized the usage of appropriate methods for engineering analysis and the usage of software products for simulation modeling and investigation of designed objects’ behavior through the use of a Frequency Analysis. The latter also includes searching for collisions that take place during the generation of the designed objects’ assembled unit. The results are useful for the purpose of acquisition of skills and knowledge in the field of expert systems application; they would help in the process of searching for creative solutions within the stages of computer-based designing of technical objects, and in the process of diagnostics of their exploitation.
