摘　　要：I-DEAS软件接口技术是通过启动ORBIX服务,运用CORBA通信协议实现的;调用Open I-DEAS二次开发类库,实现有限元数据的访问。以I-DEAS软件为前、后处理平台,基于AAR标准及Palmgren-Miner累积损伤法则,开发了焊缝疲劳虚拟仿真分析模块,推导了由设计寿命反求结构许用应力的计算公式。实例应用表明,该嵌入模块与I-DEAS软件互相配合,为设计师提供了一个高效、实用的焊缝疲劳虚拟仿真分析工具,可有效辅助设计师开展抗疲劳设计。I-DEAS software interface technology is implemented by starting ORBIX services, and using CORBA communication protocol. By calling Open I-DEAS secondary development libraries class, access to data of finite element can be achieved. Taking I-DEAS software as the pre- and post-processing platform, based on the AAR standard and the Palmgren-Miner cumulative damage principle, a virtual simulation analysis module of weld fatigue was developed, the structure stress＇formula was derived reversing from design life. The practice results show that, this module can cooperate with I-DEAS software, which provides designer a highly efficient welded structure prediction tool, so that it effectively aids designer to develop antifatigue design.
