In this paper we conducted several analysis of the simulated dynamic behavior of two passive suspension types of the trailed sprayer booms. The suspension analysis was conducted under conditions of a bump track test ISO 5008, with two levels of speed (5 km h(-1) and 15 km h(-1)) and two track profiles proposed in these standards (bumpy and smooth). It was used the simulations software MATLAB (R), SIMULINK (R) and Visual Nastran (R). The results obtained showed that suspensions of trapezoidal type have good performance at low frequencies input (omega < 0,2 Hz) while suspensions of simple pendulum type have good performance in others conditions.
