The manufacturing process of car body parts is a complex industrial process where many machine parameters and material measurements are involved in establishing the quality of the final product. Data driven models have shown great advantages in helping decision makers to optimize this kind of complex processes where good physical models are hard to build. In this paper a framework for on-line process...
The present article is devoted to a brief description of technological process of manufacturing of primer-igniter of the type “BOXER”, the development of simulation models using MatLab Simulink, development of control algorithms for the process of manufacturing products. A version control system.
The regular forging process has been the primary technology for forging workpieces manufacturing because of its well-known adaptation and performance, and it usually needs thousands of input power. In this study, the energy consumption of the conventional valve-controlled system for 22 MN forging press was analyzed firstly, and depicted that the valve-controlled system had huge energy losses. Then...
The steady state HCWE process for palm oil and the minor component have been modeled using the multivariable regression method. The MISO strategy model with two independent variables; pressure and temperature and four process outputs; overall oil yield, β-carotene, α-tocopherol and α-tocotrienol concentration have been employing to getting four multivariable equations in this process. At the first...
In this paper we extend the theory of control of discrete event systems, defined by their trace processes, to their sequential, or steady-state behavior. The control synthesis problem for finite behavior of such processes was first studied by Smedinga. Here we investigate the control synthesis problem for simultaneous control of finite and infinite (sequential) behavior of trace processes. We use...
This paper introduces a flip aware patch matching frame-work that facilitates scalable sketch recognition. An overlapping spatial grid is utilized to generate an ensemble of patches for each sketch. We rank similarities between freely drawn sketches via a spatial voting process where similar patches in terms of shape and structure arbitrate for the result. Patch similarity is efficiently estimated...
The high accuracy hydraulic static pile driver leveling is a important factor to guarantee the construction efficiency and pile quality, to meet the high accuracy of fuselage leveling during construction process, this paper analyzed the structure of body platform, and confirmed a scheme of leg movement for body leveling, and validated the rationality of the scheme by Matlab simulation.
Latex matrix is a kind of a grease with high viscosity, low heat conductivity of non Newtonian fluid, which is an important intermediate key parameter in the process of the emulsified explosive production. In the present technology condition, there are many difficulties in measuring this parameter in real-time. The design brings forward at first time a measurement of viscosity for latex matrix based...
As the heart of Flexography, laser engraving ceramic anilox roll requires that the diameter and depth of each cell is changeable, and the distribution of cell should be 30°-hexagon, 45°-quadrangle or 60°-hexagon. By modulating the laser cavity gain from step way to gradual chang way, the wave modulating technology of high repetition light pulse solves the problem of increasing absorbency of ceramic...
CMMI (Capability Maturity Model Integration)regulates the development of the project. This tool — MS Project import and export the design and implementation, the main contenders for GCGL project management tools on the part of the integrated MS Project. Microsoft Project is the world's most popular Web-based project management software. MS Project provides Gantt, WBS (decomposition of the structure)...
Servo press is more flexible for forming process than conventional press. The position control of the slider is the key technique in the servo presses. In order to achieve an excellent position control performance of the slider, a position servo control strategy of the slider in a servo press - double toggle mechanical press is proposed in this paper. The control strategy combines the Bezier curve...
This paper describes a research of online exam system based on the SSH (Struts+Spring+Hibernate)architecture. With the goal of meeting the market's needs of small-group tasks and high reliable, suitable and extendable applications, we try in the research to present a procedure of developing network system and give a layout of a developing team. We illustrate the whole process and key steps of system...
Through the experimental study of Hydraulic Control System by 6800KN Brick Press, we obtain the displacement, pressure, characteristic curve about the up and down main cylinders and floating box cylinder. On the basis of the analysis of these characteristic curve, we can work out the powder compaction curve, ejection Friction coefficient the loss of positive pressure coefficient. The result of the...
Starting with the conceptand connotation of core competitiveness and taking into consideration the status quo and model for Chinese professional sports clubs, this article scientifically analyzes the origin and formation of its core competitiveness to provide theoretical reference for designing the development strategy of the clubs and choosing the development direction of its core competitiveness.
It is an eternal subject to improve the teaching quality in colleges and universities. In the practice of teaching and teaching reform, we find that it is a systematic project to improve teaching quality, and we should not simply rely on a single element or a single link. We should take the concept of modern teaching quality management as guidance, acquire an overall and integrated quality outlook,...
The transformation of ordinary machine tools are CNC machining of small and medium enterprises to improve the accuracy of a way to reduce the auxiLiary processing time is now shorter processing time is a major means of automatic rotary tool holder so the transformation is the main part of NC.
Industrial safety plays an important part both on country economy and the people's livelihood, so it is quite essential to assess the safety of industry system. The GO-FLOW methodology is a new reliability analysis of engineering system with high efficiency, while common fault failure plays a significant part especially for the systems with high redundancy. This paper based on introducing the theory...
