摘要
装配体检索技术是提高装配体模型复用、提升工业生产力的重要一环。为加快检索速率,提出了新的零部件编码技术和Hausdorff距离的装配体相似度检索模型。首先对装配体零部件属性进行编码,将装配体模型化为数字集合;然后利用改进的Hausdorff距离计算装配体间的距离,以距离远近定义相似度的高低;最后利用实例验证了方法的正确性和有效性。
Assembly retrieval techniques are an important part of improving the reuse of assembly models and enhancing industrial productivity. To speed up the retrieval rate, the assembly similarity retrieval model with parts encoding technique and Hausdorff distance is proposed. Firstly, the assembly parts attributes are encoded to model the assemblies into a numerical set;then the distance between assemblies is calculated using the improved Hausdorff distance, and the similarity level is defined by the distance;finally, the validity and effectiveness of the method are verified by specific examples.
