The unsteady numerical simulation of fluid field and structural transient dynamic analysis of axial flow pump were carried out at three operating conditions based on fluid-structure interaction method. Numerical results show that the maximum equivalent stress of impeller occurs at the joint region of the impeller blade root and the hub, and the maximum deformation of impeller occurs at the tips of blade leading edges. The frequency-domain of the maximum equivalent stress and outlet pressure fluctuation of impeller are mainly affected by the impeller blade passing frequency.

Shale gas well casing deformation failure is extremely serious in complex fracturing process. Based on the elastic mechanics theory, the distribution law of casing’s maximum equivalent stress field with the non uniform external extrusion is calculated by the complex variable function method. Meanwhile, casing deformation failure mechanism with non uniform external extrusion is revealed. For another, the maximum equivalent stress of the casing is analyzed with the case of a/b=2 and a/b=5. The result shows that the unevenness of the extrusion load has a great influence on the casing maximum equivalent stress distribution. The findings provide technical support for casing design and selection in complex fracturing process of shale gas well.

Maximum Equivalent Stress

This study aimed at investigating the effects of the post material properties on the maximum stress in the root and maximum deformation of the restorative system. Effects of material properties of fiber post on the maximum equivalent stress in the root and the maximum deformation of the restorative system were numerically investigated. Results show that the maximum equivalent stress in the root can be decreased by 8.3% and the maximum deformation of the restorative system decreased by 10% compared with corresponding maximum values if changing Young’s modulus, Shear modulus and Poisson’s ratio in the range studied here. The maximum equivalent stress in the root is more sensitive to Young’s modulus and Poisson’s ratio while the deformation of the restorative system is more seriously affected by the Shear modulus of the post material.

Firstly, the force of an extrusion roller under actual working condition was analyzed while the contact stress between the roller shaft and the roller sleeve and the extrusion force between the roller sleeve and the material were calculated. Secondly, static analysis of the extrusion roller was carried out using ANSYS software, and conclusively, the stress concentration appears at the roller sleeve’s inner ring step. Furthermore, an optimization scheme of the setting transition arc at the step of the contact surface between roller shaft and roller sleeve was proposed, and a simulation test was carried out., Finally, the maximum equivalent stress of the extrusion roller was set at the minimum value of the objective function; the extrusion roller was further optimized by using the direct optimization module in ANSYS Workbench. The results from optimization show that the maximum equivalent stress is reduced by 29% and the maximum deformation is decreased by 28%. It can be seen that the optimization scheme meets the strength and deformation requirements of the extrusion roller design. The optimization scheme can effectively improve the bearing capacity of the extrusion roller and reduce its production cost. This can provide a reference for the design of the roller press.

Based on one-way fluid-solid coupling, a variable pitch axial fan was simulated through ANSYSY Workbench platform. With the software Fluent to describe the flow field and the software Mechanical to describe the structure field, the static structure analysis of the blades was carried out to study the strength of the blades. The flow field data were applied on the blades by interpolation. The results show that the centrifugal force plays an important role on the strength characteristics of the blades. Considering the aerodynamic load, the distribution of stress of the blades tends to be more uneven, the maximum equivalent stress reduces by 4.5% and the maximum deformation decreases by 26.6%. With the increase of flow, the maximum equivalent stress and the maximum total deformation of the blades decrease gradually.

A brief introduction of fluid-structure coupling and its classification were given, then according to the solving characteristics and application conditions of different coupling methods; sequential coupling method is chosen to calculate the stress distribution of a tide power plant tubular turbine. Stress calculations of the tubular turbine were conducted under the maximum water head, the designed water head, the average water head and the minimum water head working conditions in ANSYS Workbench. The research shows that in all of the four calculated working conditions, the maximum equivalent stress of the runner is located at the connection between the blades and the hub where stress concentration is obvious; the maximum deformation of the runner lies in the outer edge of the blades and the deformation increases from the root to the outer edge; the maximum equivalent stress of the guide vane is located at the root and the maximum deformation lies in the outer edge. The maximum value of maximum equivalent stress of the runner and the guide vane occurs on the maximum water head working condition, whereas it is far less than the material yield limit, which means that static stress will not lead to the cracks of the blade or the guide vane. But it is still necessary to avoid stress concentration appearing periodically in case it causes fatigue failure.

Abstract The spray dustless machine is an important environmental protection equipment for harnessing haze. The booster impeller of the spray dustless machine is one of the decisive factors of the booster capacity. The stability of the blade directly determines the reliability of the spray duster. In this paper, ANSYS Workbench is used to analyze the mechanical characteristics of a certain type of spray dustless blade. The results show that: under the rated condition, the maximum equivalent stress of the impeller is 55.6Mpa, which is far less than the allowable stress of the impeller material 415Mpa, the maximum deformation of the circumferential position at the bottom of the blade is 1.2mm, and other deformation positions are mainly the outer edge of the blade, which can be optimized later. The interference frequency is far away from the vibration frequency of the first two modes, so resonance will not occur.
