This paper is a further analysis of the strain tower on 1YD - JC4.After making a static analysis of 1YD - JC4 strain tower,we select the best offset point and make a dynamic analysis of it.Based on the finite element analysis software SAP2000, we set up a three-dimensional model of 1YD - JC4 strain tower of 110kv about heavy icing area,and then obtain the first six modal frequencies after making a dynamic analysis . We then draw the response spectrum curve.in the end, we select the safe and economic value of damping according to the curve.

This paper indicates a kind of research on the optimization of clamping scheme for the joint thin-walled parts in milling process .The three-dimensional model of four-flute end mill and the part are made by UG. The effect of different clamping scheme on the deformation of joint structure is simulated by the finite element analysis software ABAQUS. With the purpose of getting the minimum of the average deformation, MATLAB genetic algorithm optimizes the clamping scheme and acquires the best clamping scheme. The simulation and optimization provide an effective method for controlling the deformation due to different clamping scheme of aeronautic joint-shaped workpiece.

<p><strong>Objective:</strong> The aim of this study was to observe the influence of different occlusal contacts in a superior pre-molar structure using Finite Element Analysis. <strong>Material and Methods:</strong> A three-dimensional model of a superior pre-molar was designed to simulate three occlusion situations, namely central occlusion and two types of lateral occlusion contacts. The model presents enamel, dentin, a periodontal ligament and a fixation cylinder separately. All materials were considered isotropic, linear and homogeneous, and the contacts of each structure were perfectly bonded. On analysis software, a load was applied to an occlusal surface at 40° to the long axis on lateral contacts, and directed to the long axis on central occlusion contact. <strong>Results:</strong> The results were obtained in stress maps and the maximum values were then plotted in table for quantitative comparison, with the enamel concentrating more stress than dentin and the occlusal contact presenting the worst biomechanical behavior. <strong>Conclusion: </strong>Within the limitations of this study, it is possible conclude that: eccentric contacts have higher potential to develop abfraction lesions on the cervical region of teeth, thus increasing the magnitude of tensile and shear stresses.</p><p><strong>Keywords</strong></p><p>Finite Elements Analysis, Abfraction; Stress distribution; Occlusion, Premolar.</p>

Hood is an important part of the automobile, which directly affects the vehicle performance. This paper takes the hood as an example, first of all the three-dimensional model in CATIA was imported into Hypermesh, then it was simplified and meshed, the constrained mode and the stiffness of several conditions were calculated by Optistruct. By using the Size Optimization based on sensitivity analysis, the minimum hood mass is defined as the objective function; each component’s thickness was optimized under the prerequisite of ensuing stiffness and the first modal of hood. The results show that: the optimized hood meets stiffness requirements, the whole vehicle performance can be improved, therefore, the lightweight design in this paper is effective.
