The performance of reciprocating seals in rapping device of gasifier was studied through finite element method. The contact stress, Von-Mises stress, and friction power loss of O-ring and Sliding-ring combined Seal-ring were obtained. Meanwhile, the experimental study in performance of seal structures of rapping device were carried out. The results show that both of the seal structures are satisfied seal requirement, but compared with the Sliding-ring combined Seal-ring, the O-ring is easier to be destroyed and power loss of O-ring is higher than Sliding-ring combined Seal-ring. The results also verify the superiority of Sliding-ring combined Seal-ring in rapping device of gasifier.

The structural analysis of quad rotor frame is important since it has to withstand the forces due to aerodynamics and gravitational force due to the mounted weights. Design optimization based on finite element analysis provides an efficient methodology to meet the desired objectives related to structural elements. In the present study, design optimization based on response surface methodology has been used to optimize the shape of the arm used in the quad rotor. The objectives considered for the study include minimization of Von Mises stress and total deformation. The goal driven optimization used in ANSYS WORKBENCH has been employed for the study and arm has been redesigned to meet the set goals.

The present paper verified the effect of the interbracket distance on the force system developed by orthodontic retraction springs with two delta geometries measured during space closure when spaces between teeth are present. By using a platform transducer, five different interbracket distances were tested. Also the finite element method was applied to know the von Mises stress during spring activation/deactivation process. It was concluded that the interbracket distance and spring geometry variables have not caused significant influence on the force system resulting from activations, but activation has produced a statistical difference.

This paper presents the results of a research project obtained using theoretical, numerical and experimental methods, in order to solve the problems encountered when increasing the height of a double deep drawing sink, and the proposed solution. The analysis considers: Manufacturer limitations (eg. tool modifications, steel material changes etc.), the process parameters observed and measured during the deep drawing operation of the failure part, the theoretical fundamentals of sheet metal forming and the analysis and simulation with a computer program based in the finite element method (FEM). The analysis and simulation results using a FEM program showed that, it is possible the height increment of the sink, utilizing a variable blankholder force, to an 11% above from the fabricated parts before the application of the proposed solution but 5% less than the required final product height.

Background. This study aims to analyze the tibial component using the finite element method by cutting the tibial in frontal and sagittal planes at an angle between 1.5° (valgus and anterior tilt) and -1.5° (varus and posterior tilt). Methods. This experimental study used the finite element method as an useful tool for simulating the positioning of the tibial component in order to create a personal pre-operative planning. For the finite element method analysis, a geometrical model of a tibia from a cadaver was three – dimensionally scanned and the tibial component, polyethylene and cement, were three-dimensionally shaped in Computer-Aided Design program using material data such as Young modulus (gigapascal – GPa) and the Poisson coefficient. The analysis determined the equivalent von Mises stress, the maximum displacement of the components and the equivalent von Mises deformation. The results showed that equivalent tension and deformation have higher values in the tibia and the polyethylene, which deform faster than cement and the tibial component. In our study, we chose to simulate the tibial resection at a cutting angle ± 1.5° from neutral positioning (which is represented in frontal plane by the perpendicular on the mechanical axis and in sagittal plane by the posterior slope of 7 degree) in frontal and sagittal plane in order to find the minimum threshold from which the tibial component malalignment may begin to determine unfavorable effects. Results. Our results have shown detrimental effects begin to appear for the polyethene component at -1.5° in frontal plane, and the rest of the components at 1.5° in sagittal plane. Conclusion. This finding leads us to propose preoperative planning based on personal calculus of predefined angles, which may show the surgeon the optimal implantation position of the tibial component.

In this paper, the tee of buried heating pipe network has been investigated via the elastic-plastic finite element method. Fourth equivalent stress and distribution regularity of buried heating tees have been analyzed at different branch pipe diameter d/D and different branches length. The obtained results show that the limit length of tees decreases for the pipe diameter above DN500. The smaller diameter can lower the Von Mises stress of tees effectively. The stress of the outer wall is always greater than the internal stress.

In this work we analyze three-dimensionally using the finite element method, the level and the Von Mises stress equivalent distribution induced around a cavity and between two cavities located in the proximal and distal bone cement polymethylmethacrylate (PMMA). The effects of the position around two main axes (vertical and horizontal) of the cavity with respect to these axes, of the cavity - cavity interdistance and of the type of loading (static) on the mechanical behavior of cement orthopedic are highlighted. We show that the breaking strain of the cement is largely taken when the cement in its proximal-lateral part contains cavities very close adjacent to each other. This work highlights not only the effect of the density of cavities, in our case simulated by cavity-cavity interdistance, but also the nature of the activity of the patient (patient standing corresponding to static efforts) on the mechanical behavior of cement.

This paper presents a novel structure of the dry coal separator with vibration fluidized bed and analyzed the dynamic characteristics of the vibration parts. The natural frequency, natural mode of vibration and dynamic response are calculated based on the finite element method. The results show that the natural frequency is far from working frequency, so that the structure can avoid resonance frequency effectively. The maximum von Mises stress is 0.01MPa which are allowed in the working condition.
