The studies about orbital dynamics can be approached through numerical integrators such as Rebound, written in C, that offers several algorithms of integration and facilitates the adaptation of initial conditions and has speed of execution. The study of planetary rings serves as a laboratory for understanding the planetary formation process and the dynamics of galaxies, and Rebound is a great integration tool for gravitationally interacting N-body systems, which can deal with conservative and non-conservative forces, also with close encounters between particles and high eccentricity orbits while keeping systematic errors below machine accuracy. In this work we aim to include in the integration package of the Rebound perturbative forces in planetary rings, such as the solar radiation force, planetary oblateness and disturbances of the satellites near the rings. To validate the developed methods we will include in the package effects that alter the orbit of the particles in the rings μ and n of Uranus, such as the planetary oblateness and the forces of solar radiation. We also consider the effects due to the presence of satellites near the rings. Finally, we did an extra study of a triple asteroidal system 87 Sylvia. All the results obtained here are corroborated by the current theories, as well as the equations proposed in this work
