Abstract:
The inline 3-cylinder engine is taken as an object, the imbalance resultant rotating inertia moment and resultant reciprocating inertia moment generated by piston-crank mechanisms are analyzed. The balance theories of two different balance methods are presented and the additional moment generated through each method is derived. Three different balance conditions are proposed. The imbalance moments and mount reaction forces in each condition are calculated and compared. The powertrain mounting system design method is developed. The optimal mount stiffness not only satisfy the powertrain's natural frequencies and energy distributions but also meet the requirement for mount reaction forces in “50% balance condition”.
