A Product-Level Rapid Modeling Method for Mesh Reflector Antenna

To solve the low design efficiency problem of complex product, a product-level rapid modeling method is proposed. Parametric template library is created firstly. Then a hierarchical product assembly model is constructed by the top-down variable design. Lastly product model is generated automatically by using the technologies of position constraints and semantic mapping. The method has been applied to a self-developed modeling system for mesh reflector antennas (MRA). The results show that it can generate the product model rapidly, improve the design efficiency greatly, and provide the model data support for the follow-up analysis, optimization and adjustment process.
