摘要
基于增材制造技术思路构建了F8型空气分配阀结构模型,利用Fluent软件对F8型空气分配阀内部流道进行仿真优化,利用ANSYS进行有限元仿真进行残余应力和变形量分析,采用试验手段对仿真结果进行验证。结果表明:基于增材制造技术制造的F8型空气分配阀可以实现部件轻量化和提高列车制动性能,中间体相比于原设计可减重89.0%,最小级位常用制动和大级位制动时制动缸充风速率可分别提升13.5%和21.6%,部件残余应力和变形量可满足使用要求。提供了基于增材制造技术的F8型分配阀结构优化设计的新思路,也对其他结构复杂产品的智能制造提供了重要参考。
In this paper,the structural model of F8 air distributor valve is built based on the idea of additive manufacturing technology,and then the internal flow channel of F8 air distributor valve is simulated and optimized by Fluent software,and the residual stress and deformation are analyzed by finite element simulation using ANSYS.Finally,the simulation results are verified by experimental means.The results show that the F8 air distribution valve manufactured on the basis of additive manufacturing technology can realize the weight reduction of components and improve the braking performance of the train.Compared with the original design,the weight of the intermediate can be reduced by 89.0%.The air charging rate of the brake cylinder can be increased by 13.5%and 21.6%respectively when the minimum level service brake and the large level brake are applied.The residual stress and deformation of the components can meet the use requirements.This paper provides a new idea for structural optimization design of F8 distributor valve based on additive manufacturing technology,and also provides an important reference for intelligent manufacturing of other products with complex structure.
