Abstract

The invention discloses a bent axle rotor-bearing system dynamics experiment table electric control system, which comprises a computer controller, a preposing enlarger, an A/D converter, a magnet valve, an air cylinder, an inverter drive controller, a drive engine, a pressure sensor, a displacement sensor and a bent axle. The utility model adopts the technical scheme of bent axle rotor-bearing system dynamics test bed electric control system in the invention, which can stimulate various faults mechanism load situation, on-line test and maintaining during the working process of bent axle, etc. The invention can help people to have complete knowledge to the bent axle rotor-bearing system, which is helpful for building more accurate interdependence relationship among each design index of multiple diesel engines, and provides the theory guidance on improving the performance of diesel engine further.

Description

technical field [0001] The invention relates to an electric control system of a crankshaft rotor-bearing system dynamics test bench. Background technique [0002] The crankshaft is one of the most important components in engines such as diesel engines, internal combustion engines, and steam engines. The reciprocating motion of the piston is converted into the rotational motion of the crankshaft through the connecting rod. The power of the diesel engine, internal combustion engine, and steam engine is output through the crankshaft, and directly or indirectly drives the gas distribution system, fuel injection pump, oil pump, water pump and other components. With the development of modern power equipment in the direction of high power, high efficiency, high reliability, and low noise, the requirements for the dynamic performance of the crankshaft system are getting higher and higher. [0003] Since the crankshaft is a typical asymmetric structural part with the characteristics...
