摘　　要：目的开发多轴-蠕变疲劳寿命预测系统软件。方法采用Visual Studio 2010,编程语言用C++/CLI,Win Form开发方式,通过编制三维载荷下的临界面确定,多轴循环计数,多轴蠕变损伤,多轴疲劳损伤,蠕变-疲劳交互作用计算等各种程序,开发高温环境下的多轴蠕变-疲劳寿命预测系统软件。结果所开发的专用寿命预测软件,程序运行环境为Windows操作系统,需要NET4.0环境支持。数据采用Micro Soft Access2010,数据库管理采用了ADO.NET技术。结论软件系统适用于随机多轴载荷下高温环境中热端机械零部件的损伤状态评估和寿命预测。Objective To develop a software system for multiaxial creep-fatigue life prediction. Methods This system used for high-temperature environment was developed using C＋＋/CLI programing language based on Windows Form. The program modules mainly included the determination of the critical plane under three dimensional stress/strain states, the multiaxial cycle counting, the multiaxial fatigue damage, the multiaxial creep damage, and the creep-fatigue interaction. Results The operating environment for the developed special software of life prediction needed the Windows operating system with the support of. NET FrameWork4.0. The software used Microsoft Access 2010 to design the database and used ADO.NET as the method of database access. Conclusion The developed software system is suitable for the damage assessment and life prediction for mechanical components under random multiaxial loading at high temperature.
