The analysis of vibration performance of die casting Mg alloy instead of Al alloy used for cooling impeller was conducted.The main modal variables,including intrinsic frequency and shape were obtained by modal experiment.The specific damping coefficient (SPC) of AZ91D and A380 were measured by amplitude deamplication.Compared to the aluminum alloy cooling impeller,the magnesium alloy cooling impeller was slightly changed in modal parameter but increased in SDC by more than ten times,which highly improved the...

The analysis of vibration performance of die casting Mg alloy instead of Al alloy used for cooling impeller was conducted.The main modal variables,including intrinsic frequency and shape were obtained by modal experiment.The specific damping coefficient (SPC) of AZ91D and A380 were measured by amplitude deamplication.Compared to the aluminum alloy cooling impeller,the magnesium alloy cooling impeller was slightly changed in modal parameter but increased in SDC by more than ten times,which highly improved the vibration performance and reduce the operating noise for the impeller.

对压铸镁合金冷却叶轮替代铝合金冷却叶轮进行了振动性能的分析。通过模态试验 ,得到了叶轮的固有频率和固有振型等主要模态参数 ,同时根据振幅衰减信号测得了镁合金AZ91D和铝合金A3 80的材料减振系数 (SDC)。试验结果表明 ,镁合金对叶轮的模态参数改变不大 ,减振系数比铝合金的增加了 10倍以上 ,极大地改善了叶片的振动性能 ,减小了叶轮的工作噪声
