摘　　要：在对虚拟试验技术进行详细介绍的基础上,针对机电引信的特点,提出了引信虚拟试验系统概念及模型。在现有的CAD、CAE软件平台下,通过二次开发实现了该系统的构建。根据引信虚拟试验的要求,将系统划分为6个功能模块,对每个模块的设计方案、程序结构及模块间的接口规范进行了阐述。构建的引信虚拟试验系统可以建立带有随机偏差的引信虚拟样机,根据引信零部件间的装配关系可以自动生成引信故障树,从而完成引信可靠性分析,并可以在模拟试验环境中对引信动力学响应特性、运动的协调性等进行仿真分析从而达到对引信机构优化设计、性能评估的目的。The concept and model of fuze virtual test system are presented on the basis of a detailed study of the virtual test technology combining the characteristics of electromechanical fuzes. The system is built through secondary development in the framework of existing CAD, CAE software. According to the requirement of fuze virtual test, the system is divided into six functional modules, and the design scheme, program structure of each module and interfaces standard among modules are also described. The fuze virtual prototype with random deviations can be established by the built fuze virtual test system, and the simulation analysis of the dynamic characteristics of fuzes can be preceded under the system platform to achieve the purpose of optimal design and performance evaluation of fuze institutions.
