機械小物鋳造品仕分けへの振動応答解析の適用 藤田, 尚毅 佐藤, 正 千葉, 正克 佐藤, 清忠 伊藤, 光博 木村, 錦昭 Experimental Study Cast Iron Products Classification FFT Analysis Vibration Response Vibration response analysis is applied to a classification of cast iron products. We have studied the correlation between the mass and the natural frequency of the products. The test pieces used here are some types of water pump impellers for automobiles. It is difficult to manually classify many kinds of impellers which have similar configurations and dimensions. We have found that the frequency characteristic of test pieces, which depends on the rigidity of a disk part, can be used for the classification. As a result, we have made a characteristic map on the mass-natural frequency plane of the products, which facilitates classification. journal article 日本機械学会 1990-01-01 VoR application/pdf 日本機械学會論文集.
