摘要
利用Pro/E三维实体建模功能建立所研究的顺序增压系统进气切换机构的实体模型,并利用机构运动分析模块对该机构进行了模拟仿真和校验,最后结合CFD软件Fluent对该机构止回阀阀管内部流场进行了数值模拟计算与分析。该方法可在样机制造之前预测验证进气切换机构的设计优劣及装配干涉问题,对顺序增压系统进气切换机构的选型、优化设计等具有工程使用价值。
The 3D model of inlet switch mechanism was established by Pro/E.At the same time,with the mechanism dynamics simulation module of Pro/E,the movements of inlet switch mechanism was simulated and verified.At last,the numerical simulation and analysis for air flow in the anti-drainback valve shell was made by CFD software Fluent.This method can be used to forecast and validate the design quality and assembly,and could be applied in the selection and optimizing design of inlet switch mechanism of sequential turbocharging system.
