Distortion Optimization of Engine Cylinder Liner Using Spectrum Characterization and Parametric Analysis

Table 2

The comparison of the dominant order of distortion between the original and optimal design scheme.

Maximum distortion (μm)	1st cylinder		2nd cylinder		3rd cylinder		4th cylinder
	2nd order	4th order	2nd order	4th order	2nd order	4th order	2nd order	4th order
Original	15.35	6.54	14.86	5.99	14.95	6.03	15.75	6.64
Optimal	11.83	3.18	11.52	2.89	11.67	2.93	12.09	3.29
