A breakage point is detected as a change point from raw data and the data is divided before and after the breakage point to obtain divided data D1 and D2. When the low-pass filtering is performed on each of the divided data D1 and D2 (step S13) and the filtering for all divided data ends, time-series data whose natural frequency is removed is reconstructed before and after the breakage point. When the reconstruction data are connected at the breakage point, it is possible to restore the time-series data of the test force to the time-series data whose natural vibration of the test machine body is removed while taking advantage of a change in test force at the breakage point.
A noise removal method of removing high-frequency noise from raw data corresponding to time-series data of a test force detected by a force detector during a material test of applying a test force to a test object, comprising:
A material testing machine for applying a test force to a test object by driving a load mechanism, comprising:
