Zissimos P. Mourelatos, (Associate Professor) Paras Shah, Prashant Patel; (Graduate Students) Simulation of Piston Secondary Dynamics, Piston – Bore Contact and Piston Slap
Motivation Piston slap is an NVH phenomenon that is a strong customer dissatisfier (unusual engine noise). Noise is an important contributor to Quality, Reliability, and Durability (QRD) Piston slap is a significant contributor to the total Engine Noise, specially at cold start.
Objectives Simulate piston secondary motion Determine side thrust forces due to piston - cylinder liner contact Reduce piston slap excitation. Predict engine block vibration due to side thrust forces
