Experimental study and controlling OSS to enhance the paving machine’s efficiency

The stimulation of the oscillation screed systems (OSS) in the paving machine strongly affects the density and smoothness of the road surface. Thus, an experimental study of paving machine has been conducted to evaluate the actual effect of OSS on the index of the density and surface smoothness (D-SS) of the road. To ameliorate PM’s efficiency, a dynamic model of OSS is established and PID-Fuzzy control is used to analyze and control the excitation forces of OSS. The experimental and numerical simulation studies indicate that the D-SS of the road is strongly affected by both the tamper-pair excitation ( f 1 ) and vibrator-screed excitation ( f 2 ). In the working process of paving machine, a range of 16 ≤ f 1 ≤ 20 Hz and f 2 should be combined and used to enhance the road’s density, on the contrary, a range of 4 ≤ f 1 ≤ 10 Hz and without f 2 should be used to enhance the road’s surface smoothness. With the excitation forces of OSS controlled by PID-Fuzzy control, the paving machine’s efficiency has been clearly enhanced under various operation conditions.
