The calculation of charged particles dynamics is the initial stage in the development of an accelerator. 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*.
