摘　　要：在研究和建立了循环球转向器设计实例库之后,为了提升针对循环球转向器设计领域基于实例推理(Case-based reasoning, CBR)实例检索的效率和准确性,提出了一种基于模板检索和K-最近邻法的实例检索策略。文章首先以循环球转向器的实例检索为研究对象,简述了循环球转向器实例的表示方法;其次结合循环球转向器特点给出了该检索策略的流程和相似度计算模型;最后,通过某型号的循环球转向器的实例检索为例进行了验证。结果验证了所提出的实例检索策略的有效性,同时在工程实际中也得到了很好地验证。After researching and establishing the library of recirculating ball steering design examples,in order to improve the efficiency and accuracy of case-based inference example retrieval for the design of recirculating ball steering gear,an example retrieval based on template retrieval and K-nearest neighbor method is proposed.Strategy.The paper takes the example retrieval of the recirculating ball steering gear as the research object,and briefly describes the representation method of the recirculating ball steering device.Then,the flow and similarity calculation model of the retrieval strategy are given in combination with the characteristics of the recirculating ball steering gear.Finally,a certain model is adopted.An example retrieval of the recirculating ball diverter was verified as an example.The results verify the effectiveness of the proposed instance retrieval strategy and are well validated in engineering practice.
