LIFE CYCLE ESTIMATION OF AN AUTOMOTIVE SEAT RECLINER WITH LCF APPROACH

摘要

Automotive Seat Recliner is a mechanism that enables seat back rest to move forward and rearward about the pivot point of seat. An upgraded model of recliner with optimized dimensions is modeled so that the effort applied to unlock the mechanism reduces. The modeled Recliner was analyzed in LS Dyna to obtain the input data for fatigue calculations. Coffin Manson fatigue criterion is used to obtain results, which matches the experimental results undergone in lab.
