Traffic parameters of the road transport means are influenced beside the loads to be transported, the travel speeds, the constructive and functional characteristics by the air pressure in the tires which has a direct impact on the tire tread wear, rolling resistance, compaction, soil compaction and rolling track wear, and finally on the transport operation costs.
This paper presents the research on a transport articulated vehicle made up of an agricultural tractor and a semi-trailer, aiming at continuous monitoring of the transported load in order to determine the optimal air pressure in the tires.
In order to monitor the tire pressure, which is directly influenced by the tire load, an installation was created and placed on the articulated vehicle that continuously measures and monitors, in real time, the transported load, consisting mainly of two force transducers, two force amplifiers, a micro PLC (Programmable logic controller), an operating terminal, and the connection elements between them. The records made during experiments are managed using software specifically created for these researches.
The experiments were performed at different loads of the semi-trailer, the results obtained from the tests allowing us to determine the authenticity of the software created, on the one hand and the value evolution of the measured parameters, on the other hand.
The determined results allow the operator to make optimal decisions on the air pressure in the tire corresponding to the measured load, also taking into account the nature of the transported load, the type and condition of the rolling track.
