Application of iLogic technology in Autodesk inventor to create parametric 3D-model of a gear wheel and conduct research

The article considers the issue of creating a parametric part in Autodesk Invevtor using iLogic technology, which allows engineers to create parametric 3D models of objects, controlled by calculations written using the rules of the Visual Basic language inside the CAD program itself. The article presents an algorithm and tools for creating controlled 3D models using iLogic on the example of a 3D model of a gear wheel. Depending on the input input data, which are the transmitted torque, gear ratio and contact voltage, Autodesk Inventor performs design and verification calculation of the gear wheel, as a result of which, each time the input data is changed, the 3D model is instantly rebuilt and its geometric parameters and weight are displayed on the screen. The user-friendly interface of dialog boxes of input of initial data and output of results of calculation of a detail is created. The article provides examples of research conducted using the software Autodesk Invevtor with the use of iLogic, analysis of changes in geometrical and physical parameters of the gears for various combinations of source data, data on the time of receipt of the results. ILogic technology allows the engineer to create a library of standard and standard products in a CAD program to get a quick rebuild of the geometry of the product, which is based on the calculations in CAD programs immediately after you change the source data specification. Parameterization of three-dimensional models using iLogic technology will allow the engineer to solve various research and optimization tasks in a short time.
