optimized structure of antenna bracket | blt-金沙网上娱乐官网
antenna bracket is mainly used to connect aircraft matrix and antenna components. during the working process, it is necessary to bear the overload and the structural weight of antenna components. except for the requirements of strength, it also needs to meet the fundamental frequency requirements, to avoid resonance while using it.
the blank of traditional bracket structure is usually cast or welded. finished product is achieved by machining process. in order to meet the process requirements, the structure configuration will be restricted by several technical stricts, many force transfer paths are cut or integrated due to process constraints. the structural efficiency is limited and there are some redundant materials.
3d printing and structure optimization
based on outstanding process realization and design flexibility of 3d printing, blt is combined with related structural optimization technology, calculating and extracting the optimal force transfer path under the corresponding working conditions. also, topological structure scheme is achieved efficiently. the new design has achieved 37% lightweight, at the same time, the strength response and frequency response can meet the requirements.
