The heavy-duty truck’s gearbox housing is studied in this paper. The analysis model is built with finite element software. MPC (multipoint constraint) contact algorithm is used to simulate the connections between different gearbox housings. The strength and stiffness of gearbox housing is calculated at its low-speed load case in the first gear. The contour of the stress and displacement is obtained through the calculation results. The results show that the housing meets the design requirements and it provides a reference for optimization and improvement of the gearbox housing.

Two structural schemes of the Hong Kong-Zhuhai-Macau Immersed Tunnel were compared. In Scheme 1, the prestressed reinforcing bars were to be cut off after installation. And in Scheme 2, the prestressed reinforcing bars will be kept there as they were after installation. A finite element model for sections E12~E15 was built by using the finite element software PLAXIS with consideration to the construction process and different loading conditions to analyze both schemes. The calculation results show that they both meet the design requirements.

As an effective way of passive damping, isolation technology has been widely used in all types of building structures. Currently, for its theoretical analysis, it usually follows the rigid foundation assumption and ignores soil-structure interaction, which results in calculation results distortion in conducting seismic response analysis. In this paper, three-dimensional finite element method is used to establish finite element analysis model of large chassis single-tower base isolation structure which considers and do not consider soil-structure interaction. The calculation results show that: after considering soil-structure interaction, the dynamic characteristics of the isolation structure, and seismic response are subject to varying degrees of impact.

The Moment

In this paper, we establish the mechanical property analysis of Single-walled Carbon Nanotubes (SWCNTs) modified beam element model based on the molecular structural mechanics method. Then we study the mechanical properties of their radial direction characteristics using the finite element software Abaqus. The model simulated the different bending stiffness with rectangular section beam elements C-C chemical force field. When the graphene curled into arbitrary chirality of SWCNTs spatial structure, the adjacent beam position will change the moment of inertia of the section of the beam. Compared with the original beam element model and the calculation results, we found that the established model largely reduced the overestimate of the original model of mechanical properties on the radial direction of the SWCNTs. At the same time, compared with other methods available in the literature results and the experimental data, the results can be in good agreement.

Inner Vessel

Inner vessel in reactor assembly of sodium cooled fast reactor separates hot and cold pool sodium. The shape of inner vessel is optimized with reduced upper & lower shell diameters and toroidal redan for future Fast Breeder Reactor (FBR). This results in higher buckling strength and reduced thickness and hence reduced weight. To achieve the intricate toroidal shape with specified dimensional tolerances, a comprehensive technology development exercise was carried out successfully for the manufacture of inner vessel 30° sector. The achieved profile of the redan meets the specified dimensions and other design requirements. Spring-back observed in the sector was small. To verify the developmental exercise results, a finite element analysis (FEA) of forming of inner vessel sector was performed on finite element software ABAQUS. In this paper, FEA results and spring back are discussed. Spring back assessed is maximum at the center and relatively lower towards the edges for the redan with the chosen radius of 5980 mm.

The reasons why the producing of the difference in temperature distributing and thermal stresses of box aqueduct under solar radiation are analyzed. The difference in temperature distributing and thermal stresses are effectively simulated by the finite element software ANSYS.The calculation results indicate that concrete box aqueduct body inter-surface whatever along the longitudinal and transverse will produce considerable thermal stresses under solar radiation, and its value has exceeded the design of concrete tensile strength. Therefore, the thermal stresses under the solar radiation must be considered in the design of box aqueduct body structural. We should appropriately configure temperature reinforcing steel bar.

In the study of bridge pier’s dynamic characteristics, the modal analysis is the foundation of other dynamic analysis and is of great significance for studying other dynamic performance. Based on the dynamic theory of fluid-solid interface coupling, a 3D water-structure coupling finite element modal is established and computed by ANSYS. To verify the validity of the calculation results, the results of finite element software is compared with the analytical solutions in reference books. The analysis indicated that the results of finite element software are reasonable when the radius of bridge pier is five times the radius of water body. The ratio of water depth and the bridge pier’s height has a great influence on the change scale of bridge pier’s frequency. With the increase of bridge pier’s height-diameter ratio, the first three order natural vibration frequency is reduced.
