The need to maintain instantaneous equilibrium between supply and demand is a major constraint in the electric power system operations. Energy storage has the ability to solve this issue by allowing energy to be stored and released upon demand. Pumped hydro storage is portrayed as a viable resource that is being mostly used for storing energy. It is also considered one of best storage option that...
Safety for the occupants of medium-heavy truck is a prime consideration for cab structure design. Among front, rear impact and rollover accident, it is rollover that results in severe Casualty for occupants. Especially during the whole process of 180° rollover accidents,including two steps,the first step is 90° rollover, the second step is 90° rollover up to 180°. A new more legal and strict rollover...
In order to emerge the traditional measurement's shortage of auto body panel, we proposed the corrected FLD based on the linear path method and calculation methods. According to the above mentioned programs and the fracture defect diagnosis, we developed a CAE module for the fracture defect analysis based on VC++ environment, and solved the problems which the traditional sheet metal forming CAE software...
The operation of uncoiling and feeding is implemented in the entry section of FFX(Flexible Forming Exact) product line. Tension control in practical steel pipe production is a time-varying and nonlinear system, which has variable parameters, variable load and strong disturbance. Based on fuzzy control algorithm and empirical rules, tension variation and its change rate are determined as input variables...
Deep drawing is an important sheet metal forming process in the industry. The deep drawing of irregular square cup was investigated in this paper. To predict the damage of irregular square cup, different blank hold forces and blank shapes were studied in the numerical model. The experiment was carried out with the optimized blank force holder and blank shapes, the crack and thickness distribution...
The paper presents the Finite Elements simulation of the Cross Wedge Rolling process that has been pursued in order to investigate the mechanism of fracture and internal defects occurrence during the manufacturing of high quality steel products, such as automotive mechanical parts. The development of the simulation procedure has been articulated in different phases, in order to cope with the complexity...
Around the simulation and experiment of the drilling process of the high manganese steel, the method to set up model and relevant theories has been studied in simulation course. Utilize plastic forming finite element software, material model of high manganese steel and geometric model have been built. The drilling processing of the high manganese steel has been simulated, continuous chip and the data...
Situational simulations are dynamic, interactive, context-sensitive, adaptive environments. They further construction research by providing an interactive simulation platform that can be used to explore what-if construction scenarios and to estimate risks and contingencies. This paper extends current research to study the evolution of dynamic uncertainty in construction management projects using situational...
Hybrid models of System Dynamics (SD) and Discrete Event Simulation (DES) in the construction industry aim to provide decision makers with more accurate analysis. However, there are certain issues that can limit the applicability of SD-DES hybrid models for real construction job situations. Meaningful Level of Change (MLC) is a concept that has been proposed to prevent the time advancing issue in...
This paper deals with the problem of automatic software detection of the heat-affected area on the surface of the material sample modified by the laser beam. This detection is necessary for simulation purposes. At the beginning, the paper gives a short overview about the laser burning process that is planned to be simulated and for which the real data has to be processed. The main part of the paper...
