Application of Origami Engineering in the Formation of Complex Spring Shapes of Thin Steel Plates via Laser Quenching Forming

Abstract

In this study, the controllability of the spring performance of complex sheet spring shapes was investigated to develop complex sheet spring shapes that are based on origami engineering, with the aim of integrating laser hardening formation with origami engineering. The number of forms generated during the same development was predicted from an origami engineering perspective, and two forms that agreed with the experimental results were generated. Consequently, the rigid-body origami simulation showed that the deformation behavior differs from that of the measured values, which is considered to be in accordance with elastic-body origami. Moreover, springs with arbitrary performances could be produced by varying the processing time and form.
