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. In this paper, impact vibration of cylinder liner is obtained by the simulation analysis and acoustic pressure in the cooling water passage is evaluated by BEM analysis which boundary conditions are vibratory acceleration and acoustic impedance of the cylinder liner and water jackets. The availability of these analytical procedures are discussed comparing the calculated and measured results of the vibration response of cylinder block and pressure response in the coolant passage occupied by the air medium.
