The static and stability analysis of steel structure were taken according to steel structure work platform’s requirements and structural characteristics in a subway parking space by using the software model which is established by Pro/E software and implanted into the finite element analysis software ANSYS Workbench. The maximum deformation and stress in design load of the steel structure were calculated and the linear stress strength analysis of the key parts was carried out, also both the analysis and testing of the supporting pillar’s stability were performed. The results show that the structure model established by Pro/E and the calculation method are reasonable. Moreover, the calculation results are of high accuracy. The profile size is properly chosen and the structure bearing capacity and deformation meet the design requirements.

The Finite Element Analysis

In this study, the creep deformation in the threaded joint are discussed using a finite element method, and evaluated the influence of the dimensions of bolt and clamped parts. The stress and creep strain distributions are calculated using the Finite Element Analysis. The occurrence and the propagation of the creep deformation and influence of the creep deformation on the axial bolt force were discussed. It was found that the creep deformation occurred at the bearing surfaces and the engagement screw thread mainly at the elevated temperature. The creep deformation was a cause of the reduction in axial bolt force.

Presently, large passenger vehicles are known to have high risk of an injury due to accident and insufficient of safety regulation. The strength of seat is one of important issues that affect to injury level of passenger. Therefore, suitable structure strength and design of the seat are very important to prevent injuries and passenger life. This study was to evaluate strength of the seat structure for bus according to preliminary safety regulation of Department of Land Transport. Finite element analysis is employed by using a static load. The seat model was simplified and simulated. Stress and impact scenario between seat-back and back of manikin will be investigated. The strength and deflection of the seat will be evaluated. This study is expected to provide the seat model which will be safe and satisfied according to the regulation.

The finite element method has been applied in the area of the cervical spine since the 1970's. In the present research work, the finite element method was employed to model, validate and analyze a complete model of the human cervical spine from C1 to T1, including interconnecting intervertebral discs, ligaments and joints. The developed model of the cervical spine was validated by the experimental results presented in the literature. As the values obtained from the finite element analysis were mainly in the range of motion observed in the experiment; it was concluded that the finite element results were consistent with the reported data in the literature. Next, the validated model of the cervical spine was examined under physiological loading modes to locate the areas bearing maximum stress in the cervical spine. Finally, to study the effect of variations in the material properties on the output of the finite element analysis, a material property sensitivity study was conducted to the C3-T1 model of cervical spine. Changes in the material properties of the soft tissues affected the external and internal responses of both the hard and soft tissue components, while changes in those of the hard tissues only affected the internal response of hard tissues.

Major Factors

Accurately predicting the burst strength is very important in the casing design for the oil and gas industry. In this paper, finite element analysis is performed for an infinitely long thick walled casing with geometrical imperfections subjected to internal pressure. A comparison with a series of full-scale experiments was conducted to verify the accuracy and reliability of the finite element analysis. Furthermore, three predictive equations were evaluated using the test data, and the Klever equation was concluded to give the most accurate prediction of burst strength. The finite element analysis was then extended to study the effects of major factors on the casing burst strength. Results showed that the initial eccentricity and material hardening parameter had important effects on the burst strength, while the effect of the initial ovality was small.
