摘要/Abstract

摘要： 盒式连接可重构型架的稳定性对飞机部件的装配质量有着重要影响。为了解决当前稳定性评估方法在实施成本及有效性上的不足，从型架模块化特征出发提出基于模块服役状态的盒式连接可重构型架稳定性评估方法。首先，分析了盒式连接可重构型架服役过程，指出该过程是由作业期与空置期交替组合而成，并给出了服役稳定性及服役稳定度定义；然后，构建了基于型架关键测量特性的服役状态评价模型，实现了盒式连接可重构型架服役状态退化过程的描述及利用实测数据的空置期服役状态评估；同时，针对作业期内难以甚至无法获取测量数据的问题，提出基于多源稳定性影响因素分析并利用稳定性熵来表征服役状态退化程度的策略；最终融合空置期与作业期的评估结果构建了型架稳定性综合评价模型，相比传统的定检方法能够更简捷、有效地完成某一时间段内型架服役稳定性评估。最后，以某型垂尾盒式连接可重构装配型架后梁定位器模块为实验对象，验证了所提出方法的有效性。

Abstract: The stability of box-joint reconfigurable jigs has an important impact on the assembly quality of aircraft components. To overcome the deficiencies in the implementation cost and effectiveness of the current stability evaluation methods, we propose a method for evaluating the stability of box-joint jigs based on the module service state. Firstly, we analyzed the service process of the box-joint jig, pointing out that the process is alternately composed of an operational period and an idle period. The definitions of service stability and the degree of service stability are provided. Then, a service state evaluation model based on the key measurement characteristics of the jig is constructed, based on which the service state degradation process of the box-joint jig can be described and the service state during the idle period can be evaluated using the measured data. Meanwhile, the problem that the measured data is unable to obtain during the operational period can be solved by analyzing the multi-source stability influencing factors and using the stability entropy to represent the degradation degree of the service state. Furthermore, the evaluation results of both the operational period and the idle period are adopted to construct a comprehensive stability evaluation model, which can be applied to evaluating more simply and effectively the service stability of the box-joint jig within a certain period of time than the traditional methods. Finally, a rear spar locator module of a certain vertical tail box-joint jig is used to demonstrate the validity of the proposed methods.

Key words: service stability, box-joint, service condition evaluation model, stability entropy, stability evaluation model
