摘要：
This paper presents an analytical model for the prediction of piston secondary motion and the vibration due to piston slap. For the modeling of piston slap phenomenon, cylinder liner is modeled as a several spring-mass system that are connected by modal characteristics, and lubricant film between the piston and the cylinder is modeled as reaction force vectors which excite resonant mode of them. By comparing experimental results and analytical ones, the validity of the proposed model has been confirmed. Furthermore, it is applied this analysis to evaluate the vibration of transverse-mounted 4-cylinder engine, and is revealed the transient response to cylinder wall by piston slap.
