Universal shaft is widely used to transfer the torque and rotational movement from the drive shaft to the slave while position of one shaft can be changed. Crack used to appear in the fork part of the universal shaft in tests in a universal company. In order to solve this problem, in this paper, a finite element model of universal shaft was established with the application of Pro/E and ANSYS, and the static stiffness analysis, stress analysis and dynamic analysis were all applied in ANSYS. According to the results, the weak points were found and some improvements on the original structure were made.

The Finite Element Model

The finite element model of a novel 5-dof mould repairing hybrid machine tool is modeled by using the ANSYS Parametric Design Language (APDL), and the static stiffness of the whole machine and the sensitivity are analyzed. With the help of APDL and the concept of substructure integration, the fast reconstruction strategy to establish the finite element model is put forward. Then, the implementation strategy aimed to analyze the static stiffness of the whole machine and optimize the hinge structure are proposed. Then through the data statistics and the sensitivity analysis, the influence tendency of key flexible components affecting the static stiffness of the system are identified, which provides the guidance for parameter design of this prototype machine.

Actual Stress

To research the safety of an underground defense project and the impact to other buildings, applying basic mechanics principles, established two types of mathematical model for arch about the project, and analyzed stress in different directions of ground arch structure. The data shows that the results were very different in different mathematical models, and mathematical models should be considered as close to actual stress situation in structural analysis. In the structural analysis involved soil, spatial finite element model is more accurate and reasonable than truss finite element model.

Three Dimensional Finite Element

Caerphilly Castle (1268-70) is the first concentric castle in Britain and the second largest in the UK. The dramatic inclination of its ruinous south west tower has been noted since 1539. Comparing data from historical surveys and a terrestrial laser scan undertaken in 2015, this paper seeks to review evidence for the long-term stability of the tower. Digital documentation and archival research by architects is collated to provide data for structural analysis by engineers. A terrestrial laser scan was used to create a detailed three dimensional finite element model to enable structural analysis of the current shape of the tower made by tetrahedral elements. An automated strategy has been implemented for the transformation of the complex three dimensional point cloud into a three dimensional finite element model. Numerical analysis has been carried out aiming at understanding the main structural weaknesses of the tower in its present condition. Comparisons of four sets of data: 1539, 1830, 1870 and 2015 enabled us to determine change albeit between very different methods of measurement.
