Reliability Analysis of Drilling Mud Pump Pressure
The drilling pump is one of three major parts of a drilling rig, and is the key equipment of the drilling fluid circulation system. In this paper, the reliability of a ZCL-1600-type drilling mud pump pressure cylinder of the hydraulic system is carried on the thorough discussion. The reliability block diagram is established by qualitative analysis and quantitative calculation.
What is mathematical modeling? - Mathematics for Teaching
While there is no consensus yet as to a precise definition of this term, mathematical modeling is generally understood as the process of applying mathematics to a real world problem with a view of understanding the latter. One can argue that mathematical modeling is the same as applying mathematics where we also start with a real world problem, we apply the necessary mathematics, but …
[PDF] The Truck Mounted Concrete Boom Pump : A Dynamic
Concrete pump booms are subjected to vibrations that increase mechanical stress and shorten their lifespan. This paper aims to study the problem by considering the two subsystems, the boom and the concrete pump, that have the greatest effect on the phenomenon. The authors supply numerical and experimental tools that can analyze the problem in depth in all its complexity.

Mathematical modelling of hydraulic transients in simple
Apr 01, 2002 · 5. CONCLUSION The mathematical modelling used to develop a computer program, DYAGATS, to simulate hydraulic transients in a simple system has been described. For one thing, use is made of the so-called elastic model--also known as waterhammer-to model …
Aug 12, 2010 · As a result, there are several theories as to the source of the noise from the pump units but little concrete information to further isolate and reduce the noise generation. In this paper, a kinematic and a geometric model of a bent-axis pump have been created as part of a complete dynamic model.
Hot-Air Drying of Purslane (Portulaca Oleracea L.) As A
Sep 24, 2021 · Mathematic modelling of hot-air drying of purslane In this study, Logarithmic model as the equation (4) was chosen to fit the experimental data of the first stage. By the method of plotting, the experimental dimensionless moisture ratios are compared with those predicted by Logarithmic model as shown in Figure 6.
Modelling, simulation and identification of a mobile
This paper presents a systematic approach for the mathematical modelling and identification of hydraulically actuated large-scale manipulators. The feasibility of the overall approach is demonstrated by means of measurement results of a mobile concrete pump.
From a theoretical point of view, the concept of mathematical modelling can be represented in three parts (Fig.1): an extra-mathematical domain (D) some mathematical domain (M) mapping from the extra-mathematical domain (D) to the mathematical domain (M), resulting in outcomes that are translated back to the extra-mathematical domain (D). Figure 1.

Simulation Control of Concrete Pump Truck Boom Based on
Dec 22, 2008 · To overcome disadvantage, prove mathematical model accurate and identify parameters full, the group control was used; PSO algorithm was used to calculate the final value of every joint point, because the entire search is the process that updates the current optimal solution; all the particles are likely to faster convergence on the optimal
Discharge Flow Ripple of Axial Piston Pump with Conical
The discharge flow ripple is a crucial criterion for evaluating the piston pump. This research examines the discharge flow ripple of axial piston pump with conical cylinder block by developing a comprehensive mathematical model based upon the Bernoulli equation and the continuity equation. The novel aspect of this research is that it includes the analysis of cylinder block cone angle.
A Mathematical Introduction To Fluid Mechanics Texts In
mathematical models for fluid mechanics and gas dynamics. If solutions were not unique--which would be a big surprise--then some effect we usually ignore summary article His work covers several topics in engineering mechanics and engineering materials, such as the mechanical properties of concrete, soils, composites and rubbers, in particular the
Mathematical Models with Singularities | SpringerLink
The book aims to provide an unifying view of a variety (a 'zoo') of mathematical models with some kind of singular nonlinearity, in the sense that it becomes infinite when the state variable approaches a certain point. Up to 11 different concrete models are analyzed in separate chapters.
Modelling the interlayer bond strength of 3D printed
1. Introduction. In the past 10 years, 3D concrete printing has received increasing attention in academia and the construction industry. The technology promises more design freedom, less waste material, faster construction time, reduced cost and, most importantly, increased workplace safety [1,2].High-performance concrete mixes (HPCM) with water to binder ratios between 0.21 and 0.41 are
