Abstract
The articulated connecting rod mechanism used in large IC engines is kinematically more complex than the conventional slider-crank mechanism. Direct application of Newton's Second Law for systems of rigid bodies provides a convenient means to calculate shaking forces and moments, with the kinematic aspects handled systematically by velocity coefficients and velocity coefficient derivatives. The result is a description of the actual time variation of the shaking forces in a formulation well suited to computer evaluation. Primary and secondary shaking forces are then determined by a Fourier analysis of the time functions.
