“…The average compaction energy per unit volume of soil E can be used to evaluate the compaction performance. E can be calculated by (18) [2]. where f,, is the amplitude of displacement of drum; W is the total weight of the compactor; FE is the peak vertical exciting force; f is the frequency of motor; N,.…”

“…It is proved that a heavier frame and lighter drum will impart more compaction effort to the soil for the same static weight in their research. Reference [2] researches on improving the vibratory compaction effect by mounting the vibratory drum on the centrifugal, vertical and horizontal position of the compactor respectively. The vertical vibratory compactor is revealed to have the best compaction performance at low frequency.…”

This paper proposes and implements a novel electrically chaotic compactor. A modified time-delay feedback control method is applied to chaoize a DC motor in the compactor. The Poincare map, the bifurcation diagram and the maximum Lyapunov exponent are used to analyze the chaos in the electrically chaotic compactor. Simulation comparison not only proves that the electrically chaotic compactor offers better compacting performance than the constant speed compactor but also verifies that the electrically chaotic compactor offers the advantages of good controllability and high flexibility rather than the mechanically chaotic compactor.
