Click here to view the home page for the book. The use of vibration technology allows: increase labor productivity while saving energy and material resources; use mobile means of vibration technology and use them without bulky support structures for the perception of reactive forces; complex mechanization of construction processes. Table 1 lists the types of … Continue reading Application of Vibration Technology
Click here to view the home page for the book. The theory of vibrational and impact-vibrational immersion is connected with the study of essentially non-linear systems, in which the nonlinearity is determined both by the forces of resistance (for example, when studying longitudinal-rotational vibrations) and by the dynamics of the vibration exciter itself, for example, … Continue reading Basics Of The Theory Of Vibratory Immersion and Extraction
The rest of the book can be found here. Analyzing the data given in § 1 and 2, the effect of the interaction of the vibrating body with the ground can be explained as follows. During vibrational immersion of elements into the ground, by introducing additional sign-alternating forces and/or torques, it is possible to significantly … Continue reading Scope of Effective Application of the Vibration Method and Classification of Vibration Machines
For the rest of the book, click here. During the experimental study of the process of vibro-driven piles (O. A. Savinov, A. Ya. Luskin, M. G. Tseitlin, S. V. Plekhanova, 1954; N. A. Preobrazhenskaya, 1958; D. D. Barkan, 1959) and analysis of the results of studies of the lateral and frontal soil resistance (I. I. … Continue reading Calculation Models of the Interaction of an Immersed (Extracted) Element With the Soil
For other parts of the book, click here. Experimental data on the processes of vibro-driving and vibro-extracting were obtained for the first time by D. D. Barkan, who established the possibility of a significant decrease in the constant force required to drive a pile or extract it, in the case when the pile makes longitudinal … Continue reading The Essence of the Processes of Vibrational Immersion and Extraction. Interaction of Vibrating Bodies With Soil.
I recently wrote a paper entitled Development of a Parametric Model for the Simulation of Impact-Vibration Pile Driving Equipment. It was presented earlier today at the 2023 Spring Research and Arts Conference; the slide show for the talk is here. One of the impact-vibration hammers featured--probably the "cleanest" one in terms of the results--is the … Continue reading The S-402A Impact-Vibration Hammer
In 1859, a north Lincolnshire landowner named Rowland Winn discovered that under his land lay a valuable commodity. After digging it up, he sold 500 …How Britain lost British Steel
I found the recent paper by Metrikine et.al. (most of the authors are from Delft University) entitled "GDP: A New Technology for Gentle Driving of (Mono)Piles" interesting about combining longitudinal and rotational vibrations to install piling in a "gentler" manner. But is this new? Not really, as can be seen in this excerpt from Immersion … Continue reading Vibratory Pile Driving: Using Both Longitudinal and Rotational Vibrations Isn’t New
The development of excavator mast technology has broadened the application of pile driving equipment. Below is another way of mounting pile driving equipment, in this case using a heavy duty forklift. https://youtube.com/shorts/BnbMkty7ZBc?feature=share MKT 10B3 operating on a Manitou MHT 10210 forklift with leaders, headblock and fork mounts put together by Vulcan Foundation Equipment, Ft. Payne, … Continue reading Mounting Pile Hammer Leaders on a Forklift
In our last post A Tale of Two Coefficients of Restitution we discussed the development of equations of motion for impacting rams and piles that included a spring between them. This spring is bilinear using the coefficient of restitution. We showed that the behaviour of the ram and pile is the same with the spring in … Continue reading Comparing Rigid Piles with Semi-Infinite Piles/Wave Equation Piles
