Weght-Vibration Pareto Optimization of a Dual Mass Flywheel

By using the methodology of the multi-objective optimal design of engineering sys\uadtems, the problem of weight-vibration Pareto optimization of a dual mass flywheel is considered with the aim to study the feasibility of its application in heavy-duty truck powertrains. The results obtained show the following: the solution of the considered optimization problem does exist; the mass inertia, stiffness and dam\uadping parameters of the absorber optimized in an operating engine speed range of 600–2000\ua0rpm do exist, providing the best attenuation of the torque oscillation at the transmission input shaft. Finally, the results show the feasibility evidence for the application of weight-vibration optimized dual mass flywheel in heavy-duty truck drivetrain systems
