Machining of metals make use of thermal mechanical FEM model. Analysis of nonlinear elastoplastic finite element simulation of milling of 45 # steel material use software of DEFORM-3D that is finite element simulation technology. DEFORM-3D software could be carried out on prediction of the milling force. Through finite element analysis, distribution of stress field, strain field and temperature field of workpiece and tool is obtained under the influence of thermal mechanical. The prediction accuracy of the model was validated experimentally and the obtained numerical and experimental results were found in good agreement.
Because of the communication distance, the more nodes, the requirements of high real-time, LED lighting control system for railway vehicle carriage chooses Controller Area Network (CAN) as the communication mode to achieve centralized control in all carriages. Illuminance gathered from multi-sensors which were installed on the surface of the carriages was feed back to the Industrial Personal Computer (IPC). And then, through the incremental PID control algorithm, the IPC achieve the brightness of the lighting system intelligent control for vehicle consulting brightness intensity which according to the external environment. Experiment shows that this method is practical and effective.
Hybrid technology has already been recognized as the direction of energy conservation and reduction by world, thus it has drawn the universal concern of Engineering Machinery enterprise and the researchers. Loader as the representative of construction equipment for its high quautity and broad application over the market. In this paper, based on the categories of the hybrid power loader and combined with the latest research achievements at home and overseas,the research status of hybrid power loader has been summarized,while pointing out the problems in the development of hybrid power loader.Besides,the text also analyzes the development trend of hybrid power loader.
Three-dimensional distributions of eddy-current densities and loss densities in metals near heavy current leads in a large transformer are calculated by using the method coupled with the geometric transformation method. The method is verified through TEAM Problem 21. The local overheating regions can be found out according to the point where the maximum of the loss density is. The loss densities in the ascending flange are analyzed at the different materials and thicknesses of copper screen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
