and the impact frequency conversion module (19) is coupled with the offset recording module (18) and is used for changing the impact test frequency of the material test article and carrying out the impact test of the frequency after the corresponding conversion again when the rotation detection module (10) detects the corresponding material test article with the offset frequency larger than M in the test articles with different materials.
4. The drop hammer impact tester control system of claim 3, wherein: further comprising:
and the rotation testing module (20) is coupled with the impact frequency conversion module (19) and is used for carrying out angle rotation testing on the material test article according to the conversion frequency until the deviation frequency detected by the rotation detecting module (10) is less than M, and carrying out the impact testing.
