Optimization Design on Crankshaft-Connecting Rod Mechanism of Three Cylinder of Confined Piston Internal Combustion Pump

The optimization model of crankshaft-connecting rod mechanism of three cylinder confined piston internal combustion pump is built.The optimization design is done by Matlab language.The results of optimization is analyzed.The mass of crankshaft-connecting rod mechanism and the loss of friction power by optimization drops 33.58% and 26.60% respectively.Also the system is simulated.Effective power by optimization rises sharply.It proves that the optimization model of crankshaft-connecting rod mechanism of three cylinder confined piston internal combustion pump is correct and precise.
