Introduction. The article reviews repair of internal combustion engines for small-scale mechanization facilities.
Materials and Methods. The known positions of theoretical mechanics, general theories of chains, the theory of internal combustion engines and methods of modern control theory and the theory of electric drive are used in the work. The reliability of the results is confirmed by the experimental implementation of a rolling- brake stand.
Results. A new design of the stand for running-in and testing of small-scale mechanization engines was proposed and implemented. A distinctive feature of this devise is simplicity, reliability, high energy efficiency and low cost. The structure of the test bench of the engines of small-scale mechanization includes an asynchronous squirrel-cage motor. This device has a built-in independent cooling system, connected to the electrical network by means of an automatic switch, and a recuperative frequency converter. This converter consists of a transistor rectifier. Input chokes are installed at the input of the rectifier. Transistor voltage inverter through the DC link is connected to the output of the rectifier. The inverter supplies an asynchronous squirrel-cage motor via a circuit breaker. The electric motor is connected through a coupling with the internal combustion engine under test. The sensors for monitoring and measuring parameters for various tests are installed on this device.
Conclusions. The study demonstrated high energy characteristics, good speed and wide range of speed regulation of an asynchronous electric drive based on the space-vector modulation method. According to the results of the study, this type of electric drive quite possible can replace the electric drive based on two-unit converters due to the smaller weight and size parameters, high speed and reliability. The test stand of small mechanization engines contains an asynchronous squirrel-cage motor with an integrated independent cooling system connected via an automatic switch to an electrical network feeding a recuperative frequency converter via an automatic switch consisting of an active transistor rectifier with input chokes installed at its input, and at the output through a DC link connected to a transistor voltage inverter, supplying, in turn, by means of a circuitbreaker, an asynchronous short-circuited electric motor connected through a coupling to a test internal combustion engine on which sensors are installed, which are necessary for monitoring and measuring parameters for various tests.
