The main features of the design software system are: in the strength calculation module, using the principle of combining classical mechanics theory and three-dimensional finite element structural analysis theory to analyze and study the wind turbine in an all-round way, accurately calculate the force and deformation of each part of the wind turbine; In the design module, a powerful database linkage operation is adopted to achieve maximum automation of the design; each module is independent in operation, so multiple operations can be performed simultaneously. The system has superior performance, accurate calculation and reliable design. It has very important significance for the wind turbine manufacturer's bid preparation, selection design, strength calculation and test processing.
The technical solution can only determine the maximum stress and strain of the fan component through accurate numerical calculation, and optimize the local structure according to the calculation result, so as to reduce the material consumption; at the same time, it is necessary to develop a software for the fan design. Including theoretical design, selection design and variant design, design optimization through computer intelligent processing to improve design quality and shorten design cycle.
The specific technical solutions are as follows. Strength calculation block The normal component strength calculation and other related calculation systems mainly use the classical mechanics theory and the corresponding fan strength theory to analyze and calculate the various calculation factors, and find out the dangerous points more accurately. This method is used to deal with the problem, the speed is very fast and the result is reliable. Three-dimensional finite element strength calculation In order to more accurately analyze the real force of the complex shape of the centrifugal fan impeller in three-dimensional space, including the comprehensive analysis of stress and strain, the system uses professional three-dimensional finite element structural analysis software for analysis. Firstly, the pre-processing module is used to divide the finite element mesh into the impeller, then the finite element structure analysis is carried out through the calculation module, and finally the calculation result is observed in the post-processing module. Using this method to calculate the impeller strength, the results are very accurate and credible, which is of decisive significance for the structural optimization of the impeller.
Design theory design theory design is mainly for the special use requirements or design a new series of fans. The conditions given at design are: flow, total pressure, working medium and its density, as well as structural requirements and special requirements. This design method has become the design method of choice for most wind turbine manufacturers. Therefore, it is very important to use a computer for auxiliary selection, which can greatly reduce the design time and output complete text data. Variant design Because China's wind turbine standard grades are few and the specifications are relatively small, the variant design method is often used in the actual fan design to better meet various requirements and no trial production is required.
Other module test data processing According to the national standard (GB1236-85), the corresponding test processing method is adopted, and the test data is simply operated to obtain accurate test results, and a complete test report is output. The multi-state curve is drawn by the least square method for curve fitting, and various performance curves are drawn by data processing for the dimensionless parameter library or the parameter-dependent parameter library. Technical features An open database management system makes data maintenance very easy. Multiple programs process the same database system, making the connection between the programs convenient and fast, and realizing the interactive operation of the data.
