Research Abstract

The internal combustion engine sometimes encounters the cavitation erosion induced by piston slap. The impact vibration between the piston and cylinder liner generates the pressure fluctuation on the coolant side of the liner and leads to occur the cavitation in the case that dynamic pressure falls below its vapor pressure. Authors developed the analytical method to predict the liner vibration caused by the piston slap and the acoustic characteristic of the water coolant passage of the actual diesel engine in vacuum condition was analyzed and compared with the measured result. Moreover, theoretical method to determine the coupled vibratory characteristics of structure and water acoustic field was developed. This method employs Finite Element Method and modal analysis technique. Calculated results of vibro-acoustic characteristics of the rectangular tank were compared with the measured ones and the effect of the heavy fluid loading was elucidated.
