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.

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.

According to the plunger pump movement principle, this paper analyzed the two kind of typical force situation of the connecting rod, and obtained the theoretical maximum value of the force. The finite element analysis method was applied to analyze the structure strength of the connecting rod. The finite element model of the connecting rod was established, and the load handling and boundary condition was analyzed. The maximum stress 405MPa occurs at the transition from the small end to the link body. The average stress of the link body is 136MPa. The maximum displacement is 0.17mm, belongs to the small deformation range. The last results of the node stress and displacement show that the connecting rod can work safely.

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.

Dynamic analysis is very important in developing machine structure to sustain the required accuracy, reliability and productivity. The objective of this study is to conduct a dynamic and modal analyses of micro-milling machine. The machine designs were predicted by comparing the Finite Element Analysis (FEA) using ANSYS software and experimental hammer testing. Two micro-milling machine designs have been proposed. Natural frequency and mode shape was analyzed in modal analysis which show the result that first mode recorded frequency of 92.086 Hz for design A and 154.78 Hz for design B. Natural frequency of design B was higher than design A. From the comparision, it can be concluded that Design B was selected as a best design.

The special type of C-hook is investigated in this paper. The C-hook is designed to carry a special load, where is not possible to use classical hooks or chain slings. The designed hook is consisted of two arms that ensure the stability of the load being carried. The finite element analysis is performed for the control of the stress and deformation state in the whole hook. The fatigue analysis is performed for the check of a lifetime of C-hook.
