A Microcomputer System of Dynamic Balancing Machine for Six-Cylinder Crankshaft

The microcomputer system of the dynamic balancing machine developed for measuring the unbalance of the six-cylinder crankshaft of the automobile engine is described in detail. Four analog voltages from the measuring circuits are converted into four offset binary codes with 12 digits by A/D converter. The codes are then translated into four floating point numbers with four bytes by data processing program and calculations are made. The results of calculation, which are the magnitude and phase of the unbalance on each measuring plane or the depths to be drilled to in the selected position of crankshaft, are input to 15 LED displays to be displayed in decimal numbers. This system can be operated in either measuring or debugging (shakedown) modes, with automatic data acquisition, circuit failure monitoring and overload flashing signal.
