Owing to the lower visibility of water and flow velocity, tides, depths, terrain and others, the drilling and blasting of underwater are rather difficult. Combining with an actual rock reef project, using the Causal Analysis Graph to analyze the potential hazards which can lead to accidents on the course of drilling and blasting of underwater, and combining with the Analytical Hierarchy Process, taking...
In the research of revenue in the outsourcing process, the traditional model rarely takes the invisible benefits into account. This leads to an asymmetric information model in the revenue game between outsourcers and contractors. On this basis,with the study of outsourcers who are providing the same excitation conditions, we study the difference of effort in the contractors within the invisible and...
The paper firstly summaries the evaluation status of regional technology innovation ability, analyses the necessity that reconstruction of evaluation model, then construct the dynamic bidirectional and circulated evaluation model of regional technology innovation ability which consists of three main factors: technology innovation environment, investment and performance, and point out that it is under...
E-business (EB) is one of the most extensive and successful areas enabling the information technology, where more and more enterprises and customers set up the business within this platform. In this paper, the e-business patterns of B2B2C for the small and medium enterprises are introduced. Then the paper brings forward the logistics operation patterns which are applied within this e-business pattern...
The numerical simulation on welding process of simple structure in the paper, there are many problems have been handed. for example moving heat, latent heat of phase change and characteristic parameters of materials reduce nonlinear analysis and improve the efficiency by indirect method to calculate constructive field. ANSYS software was applied to analyze temperature field and stress field of welding...
Aiming at the exigent need of product maturity level evaluation for the third generation semiconductor microwave device and the shortages of current domestic and foreign evaluation methods, this paper extends the traditional Technology Readiness Level (TRL) evaluation method roundly from technology integration and technology dimension, establishes a structural describing and measuring model for product...
The use of transmission-line networks as periodic structures emulating many interesting metamaterial-related phenomena, such as negative refraction ([1], [2]) and cloaking ([3], [4]), has gained increasing interest in the scientific community. Transmission-line networks offer a simple way to create non-resonant, broadband structures exhibiting exotic wave propagation characteristics. A big drawback...
The engineering degree programs offered by higher education in China are currently undergoing fast development towards internationalization. There have been a number of strategies and methods out of this development process, yet most of them are oriented to importing resources from overseas without taking the existing facilities and constraints into full account. This paper first introduces a graft...
For the series of U-channel section, which has similar structure, it is easy to adjust the geometric model of U-channel section by using parametric design method, the efficiency is improved and the time for product design will be shortened greatly. By using the ANSYS Parametric Design Language (APDL), the FEA process including creating FEA model and analysis steps is discussed with the finite element...
It is always difficult to model the viscoelastic damping material accurately in a dynamics analysis, because the frequency has great influences on characters of the viscoelastic damping materials. This paper presents an iteration control program based on QR damping modal extraction method in ANSYS for calculating the structure modal damping ratio more accurately.
The square is the urban hot spot, not only the residential public life important place, but also being the superintendent's management issue. This article tries to introduce the energy concept. Take the most characteristic “Ximending” square of Taipei as the example. After photographing the pedestrian path, establishes the compression percentage, presents the carrying capacity by the immediate vision...
Finite Element Method (FEM) model was built and model analysis was executed for a thin-wall cylinder dynamometer with ANSYS, the natural frequencies and modal shapes of the dynamometer are obtained. The topological optimization was done with the variable-density method. The utilization rate of materials was improved, and the lower model frequencies were increased.
The hot-formed sheet steel is successfully applied on a vehicle by analysis of simulation test of strength, material and third point curve. The application of this material can increase not only the strength but also improve energy-absorbing efficiency. Meanwhile, the lightweight is not only achieved but also the vehicle safety crash is improved.
Fatigue is an important failure mode for swing frame of mine trunk. However, swing frame have so many attributes that it is difficult to analyze their fatigue damage using experimental measurement methods. In this paper the stress and strain analysis of swing frame is obtained by MSC. Patran software with the help of the dynamic analysis from MSC. Adams software. Improved model of swing frame is made...
The counterfeit and fake products have been rampant increasingly. It has not only affected the quality of people's lives and the stability of our society, but also hampers the development of our country's economy. How to deal with this phenomenon has became a concerning problem in the process of economic mechanism switch. This article has presented a discussion among kind of communities in market...
Mechanics analysis model of laminated solid armature is established by finite element in this article. The orthogonal method is applied in simulation experiment of laminated armature. The contact pressure between armature and rail is studied based on parameters of armature's thickness, material, layers, and length of the tail. Using range analysis method, contained by orthogonal analysis, the order...
In this paper, flat pile and under-reamed pile are stage loaded for comparative study of integrated displacement and equivalent stress. The results show that the same finite element model, the same soil, the same conditions of pile, under-reamed pile of the expansion of the integrated displacement piles has little effect, while the equivalent stress and equivalent stress distribution of the size of...
According to layered structure of anti-dip rock slope deformation and failure mechanism of the two-dimensional and three-dimensional centrifuge model test, experimental results show that the correct choice of anchor position can inhibit the transfer of the form of toppling failure to give full play the role of anchor, and foot of the slope layered structure of the anti-orientation and stability of...
In this paper, the shielding effectiveness of planar material was calculated by time and frequency domain simulation. The time domain method is to calculate time domain response of the material under the electromagnetic pulse; the frequency domain method is to calculate frequency domain response of the material under the continuous wave. By comparing time domain and frequency domain results, it is...
Wendelstein 7-X (W7-X) is a fully optimised low-shear stellarator and shall demonstrate the reactor potential of this fusion plant. It is presently under construction at the Greifswald branch institute of IPP. The W7-X coil system consists of 20 planar and 50 non planar coils. They are supported by a pentagonal 10 m diameter, 2.5 m high called coil support structure (CSS). The CSS is divided into...
