The pavement will afford the dynamic vehicle loading during using period, so it is necessary to analyze the dynamic response of pavement in order to predict pavement durable function. the most important part of pavement dynamic analysis is frequency and spectrum calculation, which is also the first part of pavement dynamic simulation. Based on composite plane theory, the pavement structure widely...
One of the demands for virtual anatomical models is parametrization, e.g., the same ”base” model but varying height, pose, body mass index, muscle volume, organ shape, etc. in order to provide a better coverage of the concerned population. We have recently reported on the development of a finite element based framework to parametrize the Virtual Population models. While the solution proposed therein...
On the situation of energy shortage all over the world, the marginal oilfields attracted more and more attention. In our country, there are many developed and undeveloped marginal oilfields. Based on its own advantages, the gravity platform has a good application prospect in the marginal oilfields. The most important load in marine environment is wave load. Consider the randomness of the wave load,...
Based on the new COSCO Building, First, the wind pressure distribution of four typical wind angers were especially studied in CFD analysis. Second, WAWS method (weighted amplitude wave superposition) was used to simulate the fluctuating wind velocity time-history, which fits Davenport power spectrum and spatial correlation. Finally, the wind vibration coefficient is obtained by applying the Gust Load...
Cold-formed steel channel sections had been widely recognized as lightweight material and its application in construction industry seen to be unlimited because it has proven in minimizing the building cost while satisfying the required strength. This paper investigates the structural behavior of cold-formed steel channel columns (without or with stiffeners) subjected to axial thrust. Computer aided...
A coring rock sample test-bed is primarily used to drill the core with appropriate size for laboratory analysis. According to the design requirements, the structure of coring rock sample test-bed is designed. On the basis of the preliminary design, the test-bed model is created with the Solidworks. And then linear static analysis and model analysis are conducted with the finite element analysis software...
The purpose of this paper is to compare the ability of solder joint with different shape (hourglass-shaped, barrel-shaped and cylinder-shaped) to resist destruction under drop impact loadings. Three 3D finite element models of VFBGA (very-thin-profile fine-pitch BGA) packages, including different shape of solder joints, are established respectively. According to the condition B in the drop test standard...
Interfacial fracturing is the most important failure mode of solder joints. In this paper, interfacial stresses of Cu pad/solder interfaces are evaluated based on the theory of interfacial mechanics and the finite element method. Effects of solder joint shapes and solder materials on the stress intensity are investigated. The results show that Sn37Pb/Cu interface has greater stress intensity than...
In this study both finite element modeling and experimental techniques are employed to study the reliability of electronics components under random vibration loading conditions. A fatigue life estimation procedure, that would help analyst to make relatively accurate prediction of induced fatigue life, Finite Element model of the test vehicle is built using ANSYS software. The model is first validated...
The combination of ANSYS and ADAMS can improve the precision of system simulation. In this paper, first, a cable-stayed space truss, consisting of stay cables, columns, and the space truss, is built in ANSYS. Second, the modal neutral file (mnf) needed in ADAMS is generated by executing the macro command “ADAMS” and then imported into ADAMS software. Third, the flexible body in the mnf file is connected...
In order to know the variation of the slope stability under external slide thrust, the soil load cell was preferred on the test platform of large-scale physical model to measure the stress in the slope body for the first time. Adopting the method of limit analysis of FEM by step load, the The external slide thrust was enhanced step by step with the method of limit analysis of FEM by step loads, the...
Introducing a suitable model for a structure to understand its behavior under different conditions of loading is very important. Mathematical modeling is the simulation of a physical structure or physical process by means of suitable analytical or numerical construct. One of suitable methods for finding deflection of a beam under different forms of loading is Finite Element Method (FEM). In this paper...
Parallel and distributed computing has been adapted to many scientific applications for aggregate computational power and memory capacity. To utilize resources efficiently and speed up application execution, tasks are split and dispatched across multiple computing elements. The ideal case is that all subtasks can finish roughly at the same time. However, this is not always achievable due to different...
The theoretical analysis of finite element method for buckling phenomenon to finite-sized shell structure is first introduced. Then, a real application using a probe for detecting the pressure inside turboprops is analyzed thoroughly with ANSYS10.0, including section profile, dimensions, and local characteristics. Based on the solved results, several rules between critical load and influence factors...
Crash-box equipped at the front end of a car, is one of the most important automotive parts for crash energy absorption. In case of frontal crash accident, it is expected to be collapsed with absorbing crash energy prior to other body parts so that the damage of the main cabin frame is minimized and passengers may be saved. In the present work, energy absorption characters of automobile crash-box...
Universal networks offer the advantage that they can execute programs written for simpler architectures without significant run-time overhead. In this paper we investigate simulations of tree machines; the fact that divide-and-conquer algorithms are programmed naturally on trees motivates our investigation. Among various proposals for parallel computing the boolean hypercube has emerged as a particularly...
