Object Of Study

Took a type of ceramics for daily use vertical type high pressure grouting machine as the object of study, study the stress and strain of its upper and lower mould plates. Established their 3D model by CAD software Pro-E, and then import them into finite element analysis software to analysis the value and distribution of the stress and strain. The analysis results can provide some reference for design, and have some engineering and practical value.

In order to obtain a higher pressure capacity for the high-pressure die with a larger sample cavity, two types of two-layer split dies with a round cylinder and a quadrate cylinder were designed based on the conventional belt-type die. Finite element analysis was performed to investigate the stress distributions and pressure capacities of the high-pressure dies using a derived Mohr–Coulomb criterion and the von Mises criterion for the cylinder and supporting rings, respectively. As predicted by the finite element analysis results, in the two-layer split dies with a round cylinder, the stress state of the cylinder can be only slightly improved; and the von Mises stress of the first layer supporting ring can be hardly decreased. However, in the two-layer split dies with a quadrate cylinder and sample cavity, the stress state of the cylinder can be remarkably improved. Simultaneously, the von Mises stress of the supporting rings, especially for the first-layer supporting ring, can be also effectively decreased. The pressure capacities of the two-layer split dies with a round cylinder and a quadrate cylinder are 16.5% and 63.9% higher with respect to the conventional belt-type die.

This paper presents results from modeling of Compressor Turbine (CT) blades for short-haul aircraft fleet occasioned by thermo-mechanical stresses in order to comprehend the occurrence of premature failure. A 3D PT6A-114A engine high pressure (HP) CT blade geometrical model was developed in commercial CAD-SolidWorks, then imported to ANSYS 15.0 environment for finite element analysis (FEA). The CT blade was investigated for transient thermal stresses from heat generated by the combustors and static structural stresses from rotational velocities of the engine which account for 80% of inertial field during flight. The results revealed that the blades could have served for another 1.44% of the time they were in service.

Abstract. The ship side flap valve underwater works with high pressure. In this paper, the valve body is analyzed using seamless connection between the finite element analysis software and Pro/E software. In the analysis, multiple load cases applied to the valve body are as follows: open condition, closed condition and seal test. The analysis result shows the maximum stress value occurs when the flap valve is open. Moreover, stress value is approximately 65 percent the range of the minimum yield strength, but the strength requirement of the valve body is satisfied. Finally, this paper presents a method for weakening the stress concentration effect by increasing the internal transitional fillet radius between the two hollow and intersectant cylinders of the valve body.

High Pressure Common Rail

The high pressure common rail injection System is one of the most advanced technologies for the diesel engine to reduce fuel consumption exhaust emissions. While the design of the high pressure common rail injector is the key for the whole system. Considering that the working pressure of fuel in the injector, a more accurate injector body model was established with the modeling software Pro/Engineer in this study. Finite element analysis technology in Ansys software was applied to calculate the strength of injector body of the high pressure common rail system under different injection pressures. And then the rationality of structure parameters and material selection of the injector body can be analyzed and verified. The research conclusions can provide the theoretical basis for the optimization design of the injector.
