Strength And Stiffness

In this paper the 3D model of the three stage helical gearbox was establish using UNIGEAPHICS (UG) firstly, and then the structure static analysis was realized by ANSYS. Accordingly the gear-box’ stress distribution, deformation can be obtained, so the strength and stiffness of the gear-box can be calculated based on the stress and the deformation results, which helps us to evaluate whether the design demand can be satisfied or not. The structure static analysis provides suggestions for the improvement of model design, and the finite element simulation to the large, heavy-duty gear-box reducer can provide technical assurance for the dependability of the production.

The connection performance of the large taper, multi-thread, variable pitch of screw threaded casing is researched by 3D finite element simulation on ANSYS Workbench. The 3D finite element model is created precisely. The stress distribution on the teeth of three kind variable pitch of screw threaded structure is studied by using the static structure of the contact analysis module. Contrasting stress distribution of the variable pitch of screw with of the equal pitch of screw under the same working condition, it is validated that design principle for the variable pitch of screw connection is correct. The influence of changes in the amount of variable pitch of screw to the whole stress distribution on teeth is discussed. The results show that the force distribution on the teeth of the variable pitch of screw connection is more uniform than equal pitch of screw, and will improve the overall carrying capacity. This study has its practical value to improve the connective performance of the threaded casing and enhance the product quality of threaded casing.

Welding Sequences

In this paper, a finite element simulation, based on abaqus software is presented for analyzing the temperature history and the residual stress states in multipass welds in stainless steel pipe. The uncoupled thermal–mechanical a three-dimensional (3D) model and a two-dimensional (2D) model are developed. The volumetric heat source with double ellipsoidal distribution for front and rear heat source, proposed by Goldak and Akhlaghi, has also been used. Furthermore, a moving heat source has been modeled by abaqus subroutine DFLUX. A user subroutine FILM has also been used to simulate the combined thermal boundary conditions. The results of both a 3D model and a 2D axisymmetric model which are compared with the available experimental measurements show good agreements. Predictions show that the axial and hoop residual stresses in a 3D model and a 2D axisymmetric model have the same distributions in all locations except the starting point of welding. The effects of welding sequences on the thermal and structural analysis are also investigated. Four types of welding sequences for circular welds of pipe have been used and thermal history and axial and hoop residual stresses are compared. Predictions show that for other locations (except the starting point of welding) there are no important differences of axial and hoop residual stresses for welding sequences and they have the same distribution along axial direction.
