【摘要】：鑒于現(xiàn)有裝配干涉檢測(cè)方法僅限于利用包圍盒排除不干涉的對(duì)象,提出軸向包圍盒和方向包圍盒的十字相交判斷方法,使得基于包圍盒即可檢測(cè)出零件在平移過程中產(chǎn)生的硬干涉關(guān)系,從而有效縮短檢測(cè)時(shí)間。利用基于擴(kuò)展結(jié)構(gòu)的層次包圍盒逐漸逼近且緊密包覆幾何模型、排除不可能干涉的零件并進(jìn)行包圍盒十字相交判斷,可大幅度減少干涉檢測(cè)的運(yùn)算量并提高算法效率�；诎鼑惺窒嘟慌袛嗯c層次包圍盒,提出面向零件平移的裝配干涉檢測(cè)算法和流程。在AeroAssem裝配設(shè)計(jì)系統(tǒng)中實(shí)現(xiàn)了該方法,通過在裝配干涉矩陣生成中的實(shí)例驗(yàn)證分析,說明所提方法是有效的和精確的,可廣泛應(yīng)用于裝配規(guī)劃與仿真等設(shè)計(jì)任務(wù)中。
[Abstract]:In view of the fact that the existing assembly interference detection methods are limited to excluding non-interference objects by using bounding boxes, a cross intersection judgment method for axial bounding boxes and directional bounding boxes is proposed. Based on bounding box, the hard interference relation of parts in the process of translation can be detected, and the detection time can be shortened effectively. The hierarchical bounding box based on extended structure is used to gradually approach and close-cladding the geometric model. Eliminating the parts that can't interfere and judging the cross intersection of bounding box can greatly reduce the computation amount of interference detection and improve the efficiency of algorithm. Based on the judgment of cross intersection of bounding box and hierarchical bounding box, This paper presents an assembly interference detection algorithm and flow chart oriented to part translation. The method is implemented in AeroAssem assembly design system. The method is proved to be effective and accurate by an example in assembly interference matrix generation. It can be widely used in design tasks such as assembly planning and simulation.
