Year: 1998
Type: article
Abstract: The piston secondary motion calculation procedure had been developed with keeping both the simple modeling and the calculation accuracy of the piston slap noise. This report describes its application for piston design parameter optimization. The analysis work was focused both on the "slap" in a lower engine speed, which excites the thrust side cylinder wall at just after the compression top dead center, and the "rattle" in a higher engine speed, which excites the both side cylinder wall for several times at around the TDC. Taguchi method was used to optimize the piston design parameters for the "slap" and "rattle". Three design parameters i. e., the cylinder bore offset, the center of gravity offset and the wrist pin offset of the piston are considered with including the interaction by each other. These results show the advantages of the numerical analysis in respect to the accuracy, cost and time compared with the experimental analysis.
