[Abstract]:The gear transmission mode is widely used in industrial production and life. At the same time of rapid social development, new requirements for the shape, size and structure of gear are also required. The requirements for the mechanical and dynamic characteristics of the gear are also higher and higher. The complexity of the gear structure and gear shape is considered when the gear structure and size are designed according to the actual needs. It takes a lot of manpower and time in solid modeling, division of grid, the given and numerical calculation of boundary conditions, especially for the general users who are not familiar with CAD, ANSYS and other engineering software. Therefore, it is urgent to make a parameterized modeling and numerical analysis software platform for a pair of gears. In this paper, the parameterized modeling and numerical analysis platform of a pair of involute gear are built, and the validity of the parameterized modeling and numerical analysis system is verified. This study first created the Visual C++ programming and the APDL technology of the ANSYS software. The parameterized modeling and numerical analysis software platform of involute spur gear has been studied. Through the systematic study of the key parameters and basic structure of involute gear, the main driving parameters and the accessory parameters and their correlation formulas are determined, and the accurate description and generation of the tooth shape are realized according to the formation principle of the involute. The main driving parameters, the shape of the involute and the parameters of the gear structure, the basic frame design, the basic function design and the user interface design are carried out for the software system. The parametric modeling and numerical analysis software of a pair of straight tooth cylindrical gears is realized by programming. The ANSYS finite element analysis is called by the batch processing mode of ANSYS and the external operation mode. Related software modules, and input a pair of gear teeth number, modulus, pressure angle, top coefficient of the tooth, top clearance coefficient and other key parameters, material properties and boundary conditions through the man-machine interface. The whole process of modeling and numerical analysis of a pair of gears is realized, which greatly improves the efficiency of the gear numerical modeling and shortens the time of modeling. The contents are as follows: 1) based on the two development of ANSYS, we build a platform for parametric modeling of a pair of involute spur gear and the function of numerical analysis. The code of the system is written with Visual C++, and the data transfer between the ANSYS software and the parameterized modeling and numerical analysis platform is realized, and the adjustment is solved. With the problems of program and other interface technology, the problem of data communication is solved by Visual Studio, and can also encapsulate the APDL command stream file.2). The key parameters of the gear are modeled as the main driving parameters. The mechanical design manual is viewed, the number of teeth, the pressure angle, the modulus, the top coefficient of the tooth and the tooth gap coefficient are five key points. As an independent parameter, the diameter of the indexing circle, the standard center distance, the tooth thickness as a non independent parameter, the size parameters are restricted and designed for the shape and size of the gear. In the use of the function of the two development of ANSYS, the APDL command flow text of the gear generated by the parameter changes is transferred to.3) to realize the parameterized modeling data and numerical analysis. According to the visual processing function, in the two development environment of Visual C++, the 3D solid data of a pair of gears, grid data, deformation data, stress data, strain data and various dynamic data are visualized and the corresponding graphics can be drawn by combining the software of the software with the software of the software itself (APDL language). By parameterized modeling of different types and different sizes of gear models, the validity of the parameterized modeling and numerical analysis software system is verified. By establishing a parameterized model of a pair of gears, and then dividing the grid and setting the boundary conditions, and finally, the static interface and the model can be used in the static interface and the model according to the actual transmission condition. The boundary conditions such as the corresponding constraint conditions and the load and torque conditions are input into the state analysis interface. The static analysis and modal analysis of the gear are carried out. The grid partition diagram, the deformation map, the stress cloud map and the modal vibration pattern are analyzed, which further verify the effectiveness of the software system.
