Abstract

Most of all road damage can be caused by dynamic loads of vehicles that fluctuate according to the type of vehicle that passes. This study aims to calculate the vertical dynamic load of the vehicle actually which occurs on road construction after through the vehicle wheel suspension mechanism. The Pneumatic cylinder that was driven by pressurized air directly weighs on the Spring and Shock Absorber that contained on the wheels of the vehicle. The load fluctuations of the medium weight category vehicle are determined by the regulation of the amount of pressurized air entering into the pneumatic cylinder chamber pushing the piston and connecting rods. The deviation that occurs during compression on the spring and Shock Absorber is substituted into the vehicle dynamic load equation by taking also the magnitude of the spring stiffness constant, and the fluid or gas coefficient of the damper. The results showed that the magnitude of the displacement when the compression force worked has significantly influenced the amount of vertical dynamic load of the vehicle that overlies the road construction. Experimental results using pneumatic actuators instead of real dynamic vehicle loads illustrate the characteristics of the relationship between work pressure and dynamic load. If the working pressure of P2 (bar) is given great, the vertical dynamic load Ft (N) which overloads the structure of the road is also greater. From the graph shows that shock absorbers have greater ability to reduce dynamic load vertically when compared to spring ability.
