Particle density is modeled by trigonometric polynomial. Space charge field is represented in the similar form. This approach is applied to beam dynamics investigation in klystron-type buncher. Numerical algorithm of polynomial coefficients calculation from the positions and impulses of model particles is formalized. As a result Coulomb field intensity is expressed in the form of integral over the set of particle phase states. Integro-differential beam evolution model is presented. Analytical expression of the variation of beam dynamics quality criterion is obtained. It makes possible directed methods using for beam dynamics optimization.
