Design and simulation of an adaptable and compact impact pile driver

Abstract Traditional impact pile drivers are designed in a serial space style and are unsuitable for narrow and small construction sites, owing to their inflexible adjacent structure. In this work, we develop a new structure with a parallel arrangement between the pull rods and precast pile, which is lighter and more efficient compared with traditional pile structures. The simulated integrated system is based on a finite element model and includes a novel impact pile driver, the pile itself, and the surrounding soil. We also use an artificial neural network to obtain a model of the stress wave pattern and allow a genetic algorithm program to be modelled as a target function for optimisation, in order to achieve the lightest total mass. Our proposed integrated framework for this compact impact pile driver demonstrates the feasibility of building flexible equipment for the future civil engineering industry.
