Abstract

PURPOSE:To shorten a weighing time and to greatly improve evaluation efficiency by evaluating residual strain with the component quantity of vibration frequency generated by vibrating a metal plate. CONSTITUTION:A vibration sensor 2 is fitted to one end of a steel sheet piece 1 and fixed with a hand or jig, and the steel sheet piece 2 is vibrated. The vibration sensor 2 measures the vibration frequency of the steel sheet piece 2, a sensor controller 3 and an analyzer 4 analyze the frequency, which is component-displayed. In this case, there are four kinds of steel sheet pieces, i.e. A (superior), B (good), C (normal), and D (abnormal) in the increasing order of residual strain, and a grating irradiation type moire topography type residual strain distribution diagram shows that A and B have no moire fringes, C has moire fringes at the peripheral part of the steel sheet piece, and D has moire fringes entirely. Those are compared to decide the quantity of the residual strain of the metal sheet.
