The idea of ​​parameterized design of parametric 3D models is an effective way to solve this problem. It is one of the basic features of Pro/ENGINGEER. Pro/E is a software developed by American Parametric Technology Corporation (PTC) and has a strong modeling function. The 3D model created in the software is a fully parameterized 3D model. / Full parameterization 0 has three levels of meaning, namely the full parameterization of the feature cross-sectional area, the full parameterization of the part model, and the full parameterization of the assembly model. Part models, assembly models, manufacturing models, and drawings are fully correlated. That is to say, after the size of the drawing is changed, the size of the parent part model will be changed accordingly; otherwise, any changes in the part, assembly or manufacturing model can also be reflected in the corresponding drawing.
Parametric design is implemented in Pro/ENGINGEER through program and relation. Program is a programmatic tool provided by Pro/E to enable human-machine dialogue. Relation (also known as a parameter relationship) is a mathematical expression between a user-defined symbol size and a parameter. Relationships capture the design relationship between features, between parameters, or between assembly components, which is a way to capture design intent. The user uses it to drive the model, and changing the relationship changes the model. Parametric Process Model The 3D solid model lays the foundation for the correct generation of 2D graphics, design modification, mechanism motion analysis, and assembly interference checking in subsequent stages. Therefore, it is important to correctly create a 3D model. Shape feature modeling is an important part of correctly building a model. Shape feature classification is the basis for building a shape feature model. Reasonable classification can make the system reasonable and easy to implement, and also provide aspects for the later parameterization.
It functionally divides features into primary and secondary features. The main features of the gear shaft of the system include curves, swivels, and the like. Auxiliary features include chamfers, keyways, etc. for each part. The main features of the inner ring plate include a rotating body, a hole, and the like. Pro/ENGINGEER provides feature-based solid modeling capabilities for product design through rotation, chamfering, rounding, and stretching. The low speed shaft model is shown in the high speed shaft model. The assembly relationship of the high-speed shaft reducer is combined with the transmission type and main parameters to determine the hierarchical relationship of the product, clarify the assembly analysis and assembly constraint types, and finally determine the parameter constraint relationship of each part. The assembly of the product is not a simple accumulation and combination between the components, but an organic connection between the individual assembly units. There are mainly key joints, threaded joints, interference joints, drive couplings and rolling slide joints.
