摘要

Acoustoelastic stress measurement of short bolts used for automobiles has established with a digital signal acquisition and signal processing system. The use of the TOF's ratio of transverse wave to longitudinal one eliminates the measurement in unstressed state. Moreover it gives precise estimation of the axial stress. The estimation of the bolt length uniformly stressed by FEM is effective for a long bolt of a length 53mm, however, it is inaccurate for a short bolt of 27mm where the axial stress distribution is complicated. Further modeling is required for very short bolts.
