Article: The simulation modelling and dynamic response for a dual-drive vibratory pile hammer considering soil nonlinearity Journal: International Journal of Information and Communication Technology (IJICT) 2026 Vol.27 No.96 pp.84 - 112 Abstract: The sinking efficiency of dual-motor driven vibration pile hammers is significantly affected by soil nonlinear hysteretic characteristics, causing synchronisation difficulties. To address this issue, this paper presents a simulation study that establishes an electromechanical coupling dynamic equation based on the Bouc-Wen model and proposes a nonlinear synchronisation control algorithm. The simulation results show that soil nonlinearity causes periodic phase difference fluctuations of ±8°, with synchronisation time prolonged by 32.5% compared to the linear model. The nonlinear synchronisation control algorithm reduces synchronisation time to 3.2 seconds under soft soil conditions, converges the phase difference to within ±2°, and achieves 26% improvement over master-slave control. The sinking displacement decreases non-linearly with increasing soil stiffness, reducing by 41.2% when stiffness increases from 5 MN/m to 20 MN/m. This study reveals the quantitative relationship between soil nonlinearity parameters and synchronisation performance, providing a theoretical basis for intelligent control.

Abstract: The sinking efficiency of dual-motor driven vibration pile hammers is significantly affected by soil nonlinear hysteretic characteristics, causing synchronisation difficulties.

The simulation results show that soil nonlinearity causes periodic phase difference fluctuations of ±8°, with synchronisation time prolonged by 32.5% compared to the linear model. The nonlinear synchronisation control algorithm reduces synchronisation time to 3.2 seconds under soft soil conditions, converges the phase difference to within ±2°, and achieves 26% improvement over master-slave control. The sinking displacement decreases non-linearly with increasing soil stiffness, reducing by 41.2% when stiffness increases from 5 MN/m to 20 MN/m. This study reveals the quantitative relationship between soil nonlinearity parameters and synchronisation performance, providing a theoretical basis for intelligent control.
