| description | The invention discloses an impact response forecasting method based on a geometric incomplete similarity principle, which belongs to the field of dynamics and comprises the following steps of: determining impact speeds of two incompletely similar models through dimensional analysis; the method comprises the following steps: assuming a value of nv, calculating betav'of two models, and calculating a relative error of deformation of the two models through finite element simulation; adjusting the value of nv, and continuously iterating until the relative error of the deformation of the two models reaches the minimum; the final betav'is used for adjusting the impact speed of the incomplete similar model, and similarity coefficients of other physical quantities are calculated at the same time; carrying out an impact test by using the processed impact speed as an initial condition to obtain data such as deformation and load of an incompletely similar model; and by using the similarity coefficient, obtaining the pred |
