Study on crankshaft runout straightening position and it's runout testing system

The measurement of parameters of the crankshaft runout was implemented online. Then the runout data was processed by adopting the least square method and vector model transformation. The experiment shows that the tested result agrees with the real crankshaft deformation. The classifier for the crankshaft straightening position using LS-SVM was set up. The set classifying system is applied to the crankshaft fillet rolling intensity and straightening machine tool, which results in a good general performance.
