It is a complex problem to study the interaction between sand castle and flowing water, which needs to consider the complexity of seawater flow and the stress of sand castle structure. The authors use the fluid-solid coupling model to establish the connection between the fluid field and the structural mechanical field, and use the finite element analysis to complete the simulation modeling of the transient process of wave impact and sandcastle foundation deformation. This paper analyzes the stress and the first principal strain of the sand castle foundation in the direction of flow velocity when the sand castle foundation is hit by waves, as a method to judge the strength of the sand castle.The best shape: the boundary value of sand castle collapse caused by strain have been determined, so as to obtain the maximum stress that a sand castle foundation can bear before collapse, which makes it possible to use the fatigue strength calculation theory of sand castle solid to carry out the quantitative calculation of sand castle durability. At the same time, the impact of waves is abstracted as wave motion equation. Finally, the finite element analysis technology is adopted to calculate the main strain of sandcastles of different shapes under the impact of the same wave, and through the comparison of the main strain, the authors get the sandcastle shape with the strongest anti-wave impact ability, which is the eccentric circular platform body.Affected by rain: the authors considered the effect of rainwater infiltration on the sandcastle's stress, and simplified the process of rain as a continuous and uniform infiltration of rain into the sandcastle's surface. The rain changes the gravity of the sand on the castle's surface. Simulation analysis is adopted to calculate the surface stress of sand castle with different degree of water seepage and different geometry. By comparison, it has been found that the smooth cone is more able to withstand the infiltration of rain without collapse.

In recent years, with the enhancement of overall national strength in China, the computer simulation technology has been developed rapidly and widely applied to engineering construction. Particularly, investment proportion of the technology in deep foundation pit engineering is immense. Yet affected by national conditions in China, the construction and application of deep foundation pit engineering have many extensive factors. It also results in insufficient vigor of finite element analysis of deep foundation pit support construction. In this way, construction problems arise frequently under the condition that there exist buildings around. With some deep foundation pit support engineering, the thesis conducts simulation analysis of the engineering through the technology of nonlinear three-dimensional finite element.Project profile

Product configuration design and simulation analysis are of critical importance in the rapid response to performance-driven product design. Product configuration design is the transition from customer specifications into physical solutions, while simulation analysis compared with testing result explains that physical solutions are correct and applicable to engineering. Configuration rules play an important role in the product configuration design. Finite element analysis (FEA) has been used widely in the simulation analysis. We could regard the simulation data of FEA as the important knowledge source of configuration rules. Then, a methodology of integration between product configuration design and simulation analysis is proposed to realize the dynamic update of configuration rules. An application of a clamping unit of injection molding machine that illustrates the proposed approach is developed at the end of the paper.

A three-dimensional finite element analysis of the soil–pile–structure interaction system is presented in this paper. The analysis is based on data from shaking table model tests made in the State Key Laboratory for Disaster Reduction in Civil Engineering, Tongji University, China. The general finite element program ANSYS is used in the analysis. The surface-to-surface contact element is taken into consideration for the nonlinearity state of the soil–pile interface, and an equivalent linear model is used for soil behavior. A comparison of the results of the finite element analysis with the data from the shaking table tests is used to validate the computational model. Furthermore, the reliability of the test result is also verified by the simulation analysis. It shows that separation, closing, and sliding exist between the pile foundation and the soil. The distribution of the amplitude of strains in the pile, the amplitude of contact pressure, and the amplitude of sliding at the soil–pile interface are also discussed in detail in this paper.Key words: soil–pile–structure interaction, shaking table model test, computer simulation, ANSYS program.

The joint simulation of Virtual Prototype Technology and Finite Element Method was utilized to perform the analysis of both strength and fatigue life of the input axis in a six-speed vehicle transmission with three axes. Firstly, the software Pro/E was used to establish a 3-D model of the input axis and its gear engagement, and the model was then imported into a software ADMAS of the virtual prototype technology to perform a dynamic simulation analysis. Secondly, the gear contact forces obtained by above-mentioned analysis were used as the loading condition of finite element analysis of the input axis to check its strength. Finally, the fatigue of meshing teeth on the input axis was analyzed to determine the fatigue life of the input axis. The results show that the static strength of input axis can meet the requirement of safe use under the working condition of input torque T=1.5kN·m, and the minimum fatigue life on the place where the stress is maximum at flexural root of a tooth is about 2 million times.
