航空发动机涡轮叶片结构复杂,制造工艺繁琐,在高温高压环境下服役需要使用特殊的材料——单晶高温合金。随着叶片几何结构的日趋复杂(如空心、薄壁等),单纯依靠经验和实验进行叶片研制和工艺开发已经落后于时代的要求,而模拟仿真技术不仅能够计算凝固过程中的各项参数,极大地丰富研发手段,而且能够精准、高效、可视化地分别针对缺陷、性能进行预测和优化,从而达到工艺-组织-性能相耦合的多尺度、全流程模拟的目标。
Aeroengine turbine blade structure is complicated, manufacturing process cumbersome, in high temperature and pressure environment require special materials used in service - single crystal superalloy. With the increasing complexity of the blade geometry (such as hollow, thin-walled, etc.), blade development and process development based solely on experience and experimentation have lagged behind the requirements of the times. However, the simulation technology can not only calculate the parameters of the solidification process, Greatly enrich the R & D means, and can accurately, efficiently and visually predict and optimize the defects and performance respectively, so as to achieve the goal of process-organization-performance multi-scale and full-process simulation.
