基于动网格6DOF技术的新型泄油阀泄油性能研究

泄油阀是实现液压式全可变配气系统中空气热量及时排除的部件,其性能好坏影响着液压式全可变配气系统的配气性能。对新型泄油阀泄油性能即泄油时间和泄油量进行数学物理建模,利用动网格6DOF技术结合单因素试验,研究入口压力、阀口开度、阀球质量、预紧力和弹簧刚度对泄油阀泄油性能的影响。单因素试验揭示了各参数对泄油质量和泄油时间的影响规律,验证了数学物理模型的正确性。

Research on the Drainage Performance of a New Type of Drain Valve Based on Dynamic Mesh 6DOF Technique

The oil drain valve removes air and heat in time in hydraulic fully variable air distribution system. Its performance affects distribution performance of hydraulic fully variable air distribution system. The mathematical and physical modeling of the drain performance of the new drain valve, namely, the drain time and the drain quality, was carried out. Using dynamic mesh 6DOF technique combined with single factor test, the influence of inlet pressure, valve opening, valve ball mass, preload force and spring stiffness on oil drain performance was studied. The single factor test reveals the influence law of each parameter on oil drain quality and oil drain time, and verifies the correctness of the mathematical physical model.
