The present invention relates to a method for controlling a vibrating pile driver when driving a pile element (4) into a ground (6), wherein the vibrating pile driver includes a vibration unit (2) connected with the same and is attached to a carrier machine (5, 1), the method comprising the following steps: detecting at least one first status parameter of the carrier machine (5, 1) and detecting at least one second status parameter of the vibration unit (2). The method is characterized in that with reference to the at least one first status parameter and the at least one second status parameter a statistical ground model is generated, and individual operating parameters of the carrier machine (5, 1) and the vibration unit (2) are adapted to the statistical ground model, in order to optimize the energy consumption and/or an advance rate when driving in the pile element (4).

A method of recognizing obstacles on operation of a vibratory pile driver of a work machine includes monitoring an acceleration signal of the vibratory pile driver during operation of the vibratory pile operator and analyzing the acceleration signal to determine the presence of an obstacle. The acceleration signal may be monitored over a time period which is determined based on an excitation frequency of the vibratory pile driver. The analysis may include comparing negative and positive half-waves of the acceleration signal. Responsive to the analysis indicating an obstacle, a system operator may be alerted, and/or operation of the vibratory pile driver may be adjusted via controller intervention.

An electrically-driven vibratory hammer is provided, which has a power supply, is wirelessly controlled, can increase the vibration amplitude and can detect the data of the vibratory hammer in real time. Through the arrangement of storage batteries, workers can also directly work through the built-in storage batteries during construction in some remote areas, without laying additional lines, and the cost is reduced. Furthermore, a movable toothed plate previously driven by a hydraulic cylinder is changed into a clamping electric cylinder capable of directly working through the storage batteries, so that a pile body can be directly clamped without an external hydraulic pump station during working. Through the improvement, the workers can directly work without additionally laying basic equipment during construction in construction sites with incomplete facilities, the construction period is shortened, the construction cost is saved, intelligent control is achieved.

An efficiency-enhanced resonant system is provided with a backing mass connected to a linear vibrator, a parasitic mass connected to the linear vibrator, a positioning spring, a connecting device, and external biasing springs. The linear vibrator provides vibrating force to the parasitic mass which is connected to the connecting device, grasping a working implement. The use of separate positioning spring and external biasing springs accommodates a tuned system that balances the reduction in backing mass movement, avoids backing mass resonance within the working range of frequencies, and maintains a minimized linear vibrator stroke within the optimal range for one-dimensional implements within desired frequency ranges. The linear vibrator provides vibration that manifests as a frequency range of the natural frequency of the combined assembly of the parasitic mass, positioning spring, external biasing springs, connecting device, and implement, so that the resonant system efficiently performs work with minimized wasted energy.
