Filed: 2002-12-10
Abstract: <P>PROBLEM TO BE SOLVED: To reduce roller vibration over a wide engine speed range by using anti-resonance; and to prevent a drift of characteristic by a secular change.  <P>SOLUTION: An engine 1 has a motor generator 2 (a motor B) being a sub-inertial mass body in addition to a flywheel 10 being a main inertial mass body. Since both are connected by an auxiliary machine driving belt 8 being a kind of spring, these members constitute a mechanical vibration system so that the roller vibration is reduced by the anti-resonance of this driving system. The motor B generates control torque in proportion to a difference in a turning angle displacement of both so as to become an electric spring, and the spring constant is controlled so that an anti-resonance frequency synchronizes with an engine speed. Thus, the vibration is reduced over a wide engine speed range. An actual resonance frequency and a damping constant are identified by measuring a response by imparting excitation torque from the motor B when stopping the engine 1.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
