摘要： PURPOSE:To obtain a displacement value which is very close to a real value by correcting all acceleration data with a mean value and integrating them to find a speed, correcting all speed data while regarding such an axis that the mean value of the speed data is zero within a range wherein displacement is originally constant as a reference line, and weighting and integrating the data. CONSTITUTION:Mean values of every 5-6 pieces of acceleration data are found and their mean value is used as a reference axis to correct and integrate all the acceleration data, thereby obtaining a chart (a) of the speed. Here, the actual displacement is as shown in a figure (b) and the speed should be zero within a range R. The reference axis S which is parallel to the inclination of speed data within the range R as shown in a figure (c) and sets the mean value of the speed data within the range R to a zero point is found and all the speed data is corrected based upon this reference axis. Further, the speed data within the range R are multiplied by a coefficient 1-e N for weighing and then integrated to obtain the waveform of displacement extremely close to a real waveform (b).
