The advancement of computer technology makes it possible to calculate particle dynamics using numerical methods with a required accuracy. During beam dynamics calculation it is necessary to take into account RF field force and self-induced Coulomb forces which also have an effect on charged particles. In this paper a model of «large particles» was chosen to simulate a space charge effect. To implement this model, a program code was written using parallel computing tools in the «C» programming language in the CUDA toolkit. The dynamics of ions with a ratio A / Z from 1 to 3.2 (A - the mass number, Z - the charge state of the ion) in the RFQ structure was calculated. The operating frequency of structure is 81.25 MHz, output energy is up to 820 keV / nucleon. Output beam characteristics (relative velocity, particle capture coefficient, beam profile, transverse emittances, longitudinal phase portrait) were determined. These results were verified by the BEAMDULAC-RFQ program.
