Starin gage를 이용한 Seat 구동용 Leadnut의 성능평가

In this experimental study, a strain gage system is used to evaluate leadnut performance for driving car seats. The tensile strain is measured at the leadnut which deforms the hole shape of leadnut from circle to ellipse. Therefore the driving force of leadscrew decreases by the deformed hole shape of leadnut. It could be concluded from this result that this experimental procedures are useful to find out the responsible mechanism that affects power seat leadnut performance.
