Full textIn this work, we study the mechanical behaviour of two types of catalysts supports produced by IFPEN and industrially used in residues hydrotreating. Those extruded supports are made of transition γ-alumina with about 70% of porous volume. The first material’s porosity is exclusively composed of mesopores (< 50 nm). The porosity of the second material is composed of both mesopores and macropores (up to 20 µm). Because of the limited knowledge of the stress fields in embedded catalysts supports in use in a reactor, this study aims at precisely and exhaustively describing the mechanical behaviour of those supports under a wide range of stresses, and identifying the possible damage mechanisms. The final objective is to better understand the influence of microstructural parameters on the mechanical properties of the supports in order to propose some leads about how to improve their mechanical strength. First, an adequate mechanical characterization methodology is set. On one hand, the tensile mechanical behaviour of the supports is studied with three-point bending and diametrical crushing tests. On the other hand, their compressive behaviour under various triaxiality rates is characterized in uniaxial and hydrostatic compression, and by spherical micro-indentation. The different damaging mechanisms are identified by imaging techniques such as scanning electronic microscopy and X-ray micro-tomography. Under tensile stresses, the supports exhibit a brittle behaviour and fracture initiates at a critical flaw. Under compressive stresses, a brittle/quasi-plastic transition is observed with increasing the triaxiality rate. The quasi-plasticity is mainly due to the densification of the macroporosity. The second part of the study consists in identifying, for each material, a fracture criterion able to represent every types of behaviour and physical phenomena observed on the same yield surface. This identification is achieved by coupling the spherical indentation tests to a numerical analysis. Fracture criteria involving hydrostatic pressure are well suited to describe the highly dissymmetric mechanical behaviour of the materials in tension and in compression. The last part of this work aims at studying the mechanical behaviour of a stack of supports under œdometric compression in order to produce stress fields more representative of those existing within the supports stacked in a reactor. This test is analysed by X-ray tomography, which allows us to determine/acknowledge the different damaging mechanisms involved in fragments and fines generation. The results illustrate the suitability of the bending and indentation tests to characterize the mechanical properties of a single support and relate them to its mechanical behaviour in a stack of supports under compression

The purpose of this paper is to design and develop a health diagnosis system of a hydrostatic spindle. Firstly, the design specifications of the presented hydrostatic spindle is based on the technical data of a given ball spindle. The main characteristics of the presented hydrostatic spindle include a radial system stiffness of 98 N/μm, an axial stiffness of 226.9 N/μm and a system flow of 4.36 L/min. Secondly, the mathematical model of axial and radial cutting force is established by using engineering algorithm. The pressure sensor data is obtained to compute the theoretical cutting force. By using the load cell the experiment cutting force of the spindle is obtain. The cutting force error between the mathematical model and the experiment test is less than 4%. Finally, the pressure sensor data and the spindle force are trained by the support vector machine (SVM), and then the accuracy is judged by the presented test data. In this paper, the accuracy rate of the experiment result is 99%. The hydrostatic spindle cutting force prognostics and health system using support vector machines is accomplished

ABSTRACT The simulation of behavior between rock mass and support system in tunneling is always to suppose the hypothesis that tunnel is under hydrostatic stress state (coefficient of lateral pressure Ko=1.0). Nevertheless, due to the variety of geological structure, the coefficient of lateral pressure has a great influence on the behavior of tunnel excavation. The purpose of this research is that the analytical solutions of nonlinear behavior of ground response curve and of support characteristic curve in a deep circular tunnel under hydrostatic stress state (Ko=1.0) and non-hydrostatic stress state (Ko≠1.0) are derived, and also consider the explicit analysis method which bases on the convergence confinement method for the Hoek-Brown failure criterion, the principle of convergence loss of equilibrium point, and effects of vertical stress, and the simple calculation spreadsheet is particularly proposed. The concept of explicit analysis method include that introducing a incremental procedure of confinement loss into the analytical solutions derived under non-hydrostatic stress state, establishing the direct calculation logic and flow chart, using a calculation spreadsheet to simply calculate and draw figures. The results obtained by the explicit analysis method (EAM) are compared with those by the finite element (FEM) program developed in this research. This comparison contains that consideration of inference factors (coefficient of lateral pressure, elastic limit of confinement loss and plastic radius, parameter of Mohr-Coulomb, confinement loss of non-supported distance, support stiffness of shotcrete, vertical stress, convergence loss of equilibrium point etc.); stress path, ground response curve, support characteristic curve, interaction curve at tunnel excavation surface, and distribution of stress-displacement around tunnel with unsupported and supported consideration, explored as a series of relatively. The influence factors of shotcrete consist of elastic modulus, Poisson ratio and thickness. The values of those parameters increase also increase that of the stiffness of shotcrete.In point of view of the parametric study of influence factors, the coefficient of lateral pressure is an important role that dominates the distribution of stresses and displacement around tunnel. The values calculated of elastic limit of convergence loss and the distribution of plastic radius are both influenced by the coefficient of lateral pressure. According to the results observed, it is shown that the comparison between EAM and FEM are almost coincident and has a good consistency under hydrostatic stress state. Concerning the vertical stress on the inclusion of non-hydrostatic stress conditions, in spite of the tunnel radial displacement has not been perfectly and correctly simulated in the reason of the different consideration of plastic potential function of strain. In addition, the results of EAM compared with those of FEM are shown a good consistency in Hoek-Brown and Mohr-Coulomb models. The explicit analysis method proposed in this research is an efficiency analysis method which could have a good simulation of non-linear behavior of ground response curve and of support characteristic curve in tunneling.
