Test and Analysis on Assembly Deformation of Diesel Engine Cylinder Liner

The measurement of deformation of one diesel engine water cooling cylinder liner under free condition and assembly load case is carried out by V-INCOMETER testing system. The basic principles of radial deformation for this cylinder liner are obtained through the test data Fourier transformation. And the affect principles of cylinder liner original distort, which results from mechanical machining and heat treatment process, to the cylinder liner assembly deformation are carried out.
