Drilling frame on TD165CH Down-The-Hole Drill that has large slenderness ratio and be longer than 10m is one component of Down-The-Hole drill which is mainly subjected to load.In the process of drilling, drilling frame is not only subjected to loads which are like tensile, compression and torsion and so on, and be under the influence of impacting and vibration of impactor,the situation of force is complicated.By analysing of working condition of Down-The-Hole drill,there get all kinds of limit states of typical working conditions, and then using Ansys doing finite element analysis, there get distribution of the stress and strain of drilling frame and the result of modal analysis to check whether drilling frame meets the requirements of strength and stiffness or not,and whether it is possible to resonate with the impactor or not.By analysis,Structure strength and stiffness of drilling Frame on TD165CH Down-The-Hole drill meet the requirements of practical engineering, and drilling Frame does not resonate with the impactor.

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.

Coal mine mobile refuge chamber, as the important equipment of underground refuge system, has a close relation to the life safety of the miners. At present, there are a lot of production refuge Chamber manufacturers, but they do not enjoy a unified standard in shape or size. This paper focuses on the establishment of the KJYF96/10 mobile refuge chamber model by Solidworks and adopts the structural finite element analysis by Simulation, drawing a conclusion of refuge chamber stress and displacement cloud chart. It is expected to offer an effective reference to improving the structure strength and reducing design costs.

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.

To enhance the structure strength and working life of the existing ladder-type chain connector, and chain connector productivity and manufacture craftwork. The ANSYS finite element software is utilized to simulate contact non-linear finite element analysis of ladder type chain connector. And the static and dynamic experiments are carried on several samples. Finite element simulation results show that the main part of stress concentration is in teeth roots; experiments results show that the teeth roots are the fragile parts in the chain connector, the results of finite element analysis is conformed to the results of the experiments, thus that the ANSYS finite element software is utilized to simulate contact non-linear finite element analysis of chain connector is reasonable. Because of the shortcoming of straight tooth chain connector, then promoted a chain connector of cambered surface tooth structure. Through the analysis, it shows that cambered surface can augment the contact areas in teeth, and prevent partial loading in teeth meshing. When chain connector manufactured, clamping tongs are quite complex, but the petal-type clamps structures are adopted, that can carry out volume-producing, thereby, and the productivity and processing precision are improved.
