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®; SIMULINK® and Visual Nastran ®. The results obtained showed that suspensions of trapezoidal type have good performance at low frequencies input (w < 0,2 Hz) while suspensions of simple pendulum type have good performance in others conditions.
