AKTUATOR PNEUMATIK SEBAGAI SIMULATOR BEBAN DINAMIS VERTIKAL PADA MEKANISME SUSPENSI RODA KENDARAAN SEPEREMPAT

Abstract

This study aims to determine the suspension characteristics of vehicles that are loaded vertically. Pneumaticcylinders as actuators will be driven by compressed air and directly overload the vehicle's wheels. Deviations that occurduring compression in Spring and Shock Absorber are substituted into the vehicle dynamic load equation. Experimentsare carried out using pneumatic actuators that replace the real dynamic load of the vehicle. The results show that themagnitude of the displacement when the compression force works is significantly affected by the vertical dynamic loadof the vehicle which weighs on road construction. From the graph shows that the shock absorbers have a greater ability toreduce dynamic loads vertically when compared to spring capabilities. The shock absorber is able to reduce the load by55.85%, so that the vertical dynamic load of the vehicle, FDvk which loads the road structure is equal to, 16204 N.
