A strength analysis on a large-scale horizontal vacuum tank, a dry equipment of the “ two million” large transformers, will be done in this article. Using the means of finite element analysis and two different unit-setting models, we compare the two results getting from the two units. Different lengthen styles of vacuum tank’s reinforced bead will be discussed, as well as different processing styles of welding parts model-setting in ANSYS.

Tubular Joint

For large scale multiplanar tubular joints used in practical engineering, the brace/chord intersection is a critical position as failure usually occurs here due to the weak bearing capacity of the chord in radius direction compared to the strength of the braces in axial direction. To improve the ultimate strength, different reinforcements can be used to strengthen the structures. Inner plate reinforcement is a relatively new strengthening method compared to conventional reinforcing methods. As there is no corresponding guideline which can be used for the design of inner plate reinforcing joints, it is necessary to investigate the failure mechanism of such tubular structures. Both experimental test and finite element analysis are carried out in this study to investigate the static behaviour of multiplanar tubular joint reinforced with inner plate. In the experimental work, the stresses distribution and development of the specimen is monitored, and the failure mode is observed. From the experimental results, both the failure process of the multiplanar tubular joint and the reinforcing efficiency of the inner plate were analyzed. Using finite element analysis, the failure process of the specimen is also analyzed step by step. The finite element results agree reasonably well with experimental measurements.

In order to study the basic mechanical property of cast-in-place stiffening-ribbed-hollow-pipe reinforced concrete girderless floor, and similarities and differences of the structural performance compared with traditional floor, we carried out the destructive stage loading test on the short-term load test of floor model with four clamped edges supported in large scale, and conducted the long-term static load test. Also, the thesis conducted finite element analysis in virtue of ANSYS software for solid slab floor, stiffening-ribbed-hollow-pipe floor and tubular floor. The experiment indicates that the developing process of cracks, distribution and failure mode in stiffening-ribbed-hollow-pipe floor are similar to that of solid girderless floor, and that this kind of floor has higher bearing capacity and better plastic deformation capacity. The finite element analysis manifests that, compared with solid slab floor, the deadweight of stiffening-ribbed-hollow-pipe floor decreases on greater level while deformation increases little, and that compared with tubular floor, this floor has higher rigidity. So stiffening-ribbed-hollow-pipe reinforced concrete girderless floor is particularly suitable for long-span and large-bay building structure.

To ensure the safe use of single shear hydraulic lift platform for processing and manufacturing railway vehicles. This paper analyzes the use conditions of single shear hydraulic lift platform, and makes a contact nonlinear finite element analysis on various typical use conditions. The positions of parts subject to danger can be found out through the results of static strength analysis, which finds out the weaknesses and prejudges the failure trend of parts, and which provides guidance for prejudging the faults in actual production and can prevent occurrence of accidents.

Uniform Scaling

Control of temperature in large-scale manufacturing environments is not always practical or economical, introducing thermal effects including variation in ambient refractive index and thermal expansion. Thermal expansion is one of the largest contributors to measurement uncertainty; however, temperature distributions are not widely measured. Uncertainties can also be introduced in scaling to standard temperature. For more complex temperature distributions with non-linear temperature gradients, uniform scaling is unrealistic. Deformations have been measured photogrammetrically in two thermally challenging scenarios with localised heating. Extended temperature measurement has been tested with finite element analysis to assess a compensation methodology for coordinate measurement. This has been compared to commonly used uniform scaling and has outperformed this with a highly simplified finite element analysis simulation in scaling a number of coordinates at once. This work highlighted the need for focus on reproducible temperature measurement for dimensional measurement in non-standard environments.
