Method for dynamically optimizing structure of valve plate of aviation plunger pump based on instantaneous flow model

The invention discloses a method for dynamically optimizing the structure of a valve plate of an aviation plunger pump based on an instantaneous flow model. The method is established on the basis of the instantaneous flow model of the aviation plunger pump, and comprises the following steps of: selecting the radius r2 and the shift angle theta of a shock relief vent as the design variables for the dynamic structure optimization of the valve plate of the aviation plunger pump; randomly generating two groups of initial parameter vectors and substituting the initial parameter vectors into the instantaneous flow model of the aviation plunger pump to obtain instantaneous flow values of the aviation plunger pump under the two groups of parameter vectors; selecting the instantaneous flow pulse amplitude of the aviation plunger pump as a target function, comparing two target function values F(XL) and F(XH) and modifying structure parameters in real time through rotation transformation and contraction transformation t
