An intelligent forecasting method for local short term electric load is proposed based on fuzzy clustering and partitioned support vector regression (PSVR). Firstly, the scheme of this method is introduced. Then, prediction time was partitioned into three sections adaptively by means of fuzzy C-means clustering, according to the characteristics of local power load pattern. Sub-models for each section...
In order to model the gearbox and global wind turbine system with higher accuracy in short time, this paper focuses on the methods of multi-body dynamic modeling and wind turbine dynamic simulation on the platform of S4WT. By introducing the multibody system and super element approach, a steady-state response is simulated on one 1.5MW gearbox. Through calling S4WT parametric model, a dynamic response...
Using the ANSYS finite element analysis software to establish a SOLID92 as the basic unit of the finite element model. We use ANSYS to analysis the Qianjiaying of Tangshan coal mine shaft sheave, from the quiet intensity of the head sheave to evaluate its safety. It will give reasonable advice for the similar design.
In the virtual reality technology, simulate the different weather can increase the realism, the particles of the rain and snow is usually realized by the particle system. While, when the particles reach to certain orders of magnitude. It is difficult to achieve real-time effects. LOD technology means control of details, based on the research of particle system and LOD technology, the author puts forward...
In order to study the dynamic characteristics of centrifuge facility-vibration shaker system, In the establishment of centrifuge facility-vibration shaker system multi-body dynamic model based on virtual mocking technology, the virtual dynamic model of the entire centrifuge facility-vibration shaker system more close to reality is built up by the transmission of finite element of flexible centrifuge...
The domestic platform is composed of the independent and controllable software and hardware equipment, such as CPU, operating system, database and middleware. In order to promote the application of the domestic platform, the simulation verification environment and the integration verification technology are deeply studied in this paper. Firstly, this paper designs the target model of the simulation...
Computers have been used in many fields, for example, design, fabrication and installation of the offshore oil and gas exploration and production structures. As computer processor and memory have been rapidly developed in the past decades, computers have been used much more widely. This paper will mainly discuss the computer application in Offshore Engineering. Because of the particularity of Steel...
