This paper presents the fundamentals for eliminating overshoot and vibration produced by dynamic loading, especially impact force in material tests. Overshoot and vibration are usually eliminated from original values with dampers and filters, since they prevent determination of true loading values. The fundamentals make it possible to determine values for eliminating undesirable phenomena.Three model sensors based on the above fundamentals were made to confirm effectiveness. From experimental results, the validity of the fundamentals as a load sensor for eliminating the overshoot and vibration was confirmed practically.
