Roll bending technologies for highly accurate compression ring of automobile engine

$15.00

Compression piston rings are essential parts of an automobile engine. The rings are produced by four-roll bending using high-tensile steel alloy. However, defective phenomena of the distortion and the gap, etc., occasionally occur. This research aims to improve the compression ring with more accurate dimensions by using FEM analysis and experimentation. It was found that these defects were reduced through arrangement of the roll and intermesh.
