摘要
通过基于三维数字化模型的装配工艺仿真技术,快速实现发动机全生命周期各环节的设计迭代优化,从而提高航空发动机研发效率、降低研发成本、缩短研发周期;在可视化的数字环境中建立航空发动机低压涡轮装配工艺模型,进行装配路径规划、装配过程仿真,以验证产品的可装配性及其工艺过程合理性;仿真结果显示,在使用拧紧工装进行内部螺钉的拧紧操作过程中,拧紧工装单次拧紧超过一定角度后,与引气管焊接组件发生干涉;在不改变装配工艺的前提下,考虑修改工装设计以优化装配操作,避免了制造后设计更改。航空发动机数字化装配仿真分析研究,探索了使用仿真工具进行三维数字化装配规划、仿真分析与设计制造协同工作模式,为下阶段仿真技术研究的体系化与标准化建设奠定了基础。
By using 3-dimensional digital process simulation,aircraft engine lifecycle design and optimization is made to improve development efficiency and to reduce cost and time.In visualized digital environment,assembly model of a certain type of aircraft engine turbine is modeled.Furthermore,assembly path planning and process is simulated and analyzed to verify assemblability and feasibility of process design.Result shows that tightening tooling interferes with component after rotating for a certain angle during assembly operation.Tooling is redesigned accordingly to avoid wasting instead of process change.Study ondigital assembly simulation of aircraft engine low pressure turbinecontainsdigital assembly planning,simulation method and design-manufacturing synergy mode.Thus contributes as fundamentals for systematization and standardization of simulation technology in next phase.
