Piston Dynamic Analysis and Vibration Response Research based on Analytic Method
Based on the analytic method,the piston dynamics model of gasoline engine is established to analyze the second-order motion of the piston,and the forced vibration response of the cylinder liner is predicted by taking the cylinder clearance,piston pin bias,piston and cylinder liner profile into full con-sideration.The results show that the piston dynamic model established by analytic method has high ana-lytical accuracy.
