机械振动对A356和AZ91D消失模充型的影响
Influence of mechanical vibration on the filling capacity of A356 and AZ91D in lost foam casting
摘要
Abstract
Mechanical vibration was applied during lost foam casting (LFC) process of A356 aluminum alloy and AZ91D magnesium alloy. The vibration direction was the same as the flow direction, and the influence of mechanical vibration at different frequency and amplitude on the filling capacity of A356 and AZ91D under lost foam casting was studied. The filling mathematical model was established in lost foam casting by the vibration, and the filling capacity was analyzed by the fluid dynamics and heat transfer, and the influence of the vibration on the filling capacity of the alloys was explained. The results show that the filling capacity of the alloys increase with the vibration frequency and amplitude increased, and it is obviously increased applying mechanical vibration to be at the peak acceleration between from 1g to 4g. The calculated results of filling capacity of the mathematical model are basically consistent with the experimental results.关键词
