Abstrakt

Methods are outlined that can be employed to reduce the dynamic components of interaction forces between the vehicle engine and the car body, taking into account the main sources of vibration in the engine. The transmitted forces arising due to the reciprocating motion of the pistons in a two-cylinder engine are calculated. The amplitude and frequency characteristics are used to develop a method for controlling the engine mount stiffness and damping depending on the angular velocity of the crank shaft motion. The study explores the feasibility of damping control in the mount through the use of magnetorheological (MR) dampers operated in the squeeze mode.
