Computerized Laboratory in Science and Technology Teaching: Course in Machine Elements

The Computer registration of physical and mechanical quantities gives a lot of possibilities of machine elements and mechanisms research. The advantages of well-organized computer laboratory both technical and methodological, namely: Registration and on-line observation of a number of processes with random speed; replacement of high-cost specialized laboratory equipment; mathematical data processing; solving educational problems by modern technologies; dealing both with machine objects and ICT by oneself. The purpose of the paper is to present the results of implementation of universal computer system of registering physical and mechanical quantities researching elastic coupling in the laboratory in Machine Elements at Higher School of Transport, Sofia, Bulgaria. The results are obtained by special stands and the quantities are registered by an universal interface and software. After mathematical processing a number of characteristics and properties important for practice have been obtained such as diagram of friction and dumping in the coupling, shaft angle speed, Fourier analyzing, etc.
