MECHANICAL CHARACTERISTICS OF ELECTRO DRIVE SYSTEM WHITH SINGLE TREE PHASE QUASYRESONANCE CYCLOCONVERTER
- AUTHOR(S):
C. Petkov
- ABSTRACT:
The paper shows the result of analyze and study of mechanical characteristics of electro drive system based on direct frequency convert- er and induction motor. The analyze is done on theory of T – equivalent scheme by reading of higher harmonics action upon mechanical property of the drive system. Questions about nonsinosoidal power supply properties of induction motor are considering also.

IMMUNE METHOD FOR MAKING MANAGEMENT DECISIONS
- AUTHOR(S):
M. L. Lazarov
- ABSTRACT:
This paper presents an immune method for making management decisions. The method is based on the principles of a cellular immune response. Immune method for management decision is fully applicable in the process of generating management solutions. The method aims to eliminate subjectivity at making management decisions. The method successfully overcomes the limitations associated with the mathemati-
cal modeling of economic tasks. The method has the capability of learning and self-study.

- ABSTRACT:
Increasing the efficiency of lathe machining parts with complex shapes by CNC machines in a non-stationary cutting, based on an opti- mization of the many passing processing in probabilistic formulation of the problem and the analysis of different variants of cutting the addi- tive is actual task, solving which is possible with the development of a mathematical model for determining the time of cutting, durability and
tool wear, as with many passing processing in non-stationary conditions of cutting, so and with variable cutting during the working stroke of the tool.

DESIGN OPTIMIZATION OF A TECHNOLOGICAL GEAR SHAFT
- AUTHOR(S):
V. Nikolov, G. P. Tonkov
- ABSTRACT:
The research focuses on the design and static load capacity of a technology gear shaft. A new design of the shaft is proposed, consistent with the functionality of the mechanism. The design of the shaft is optimized in dimensions, workability of production, and i nstallation. The technological mechanism works in harsh operating conditions as the gear is open and shock loaded. This adversely affects the other elements and aggregates, including the studied shaft. Design and optimization of the shaft in this operational mode is performed in the software environment of specialized software MITCalc. The results are rich illustrated. They can be used in designing various types of shafts and their multicriteria optimization.
