Description
technical field [0001] The invention relates to the field of preprocessing of mechanical experiment data, in particular to a method for preprocessing mechanical experimental data based on a mechanical model. Background technique [0002] In the mechanical experiment test for material performance, it is necessary to implement different test methods for each characteristic of the material and obtain relevant experimental data. When the relevant data volume is large, it is necessary to pre-process the data to obtain relatively simple but accurate experimental data. , so that reasonable material performance analysis can be carried out later. [0003] The material test data obtained through experiments sometimes has a large amount of data due to different loading conditions, and generally requires preprocessing of such experimental data to obtain accurate mechanical properties of the material. On the one hand, it improves the processing ability of the material performance respon...
