Weight-Vibration Pareto Optimization of a Dual Mass Flywheel

By using the methodology of the multiobjective optimal design of engineering systems, we consider the problem of weight-vibration Pareto optimization of a dual mass flywheel with an 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 damping parameters of the absorber optimized in an operating engine speed range of 600–2000 rpm exist and provide the best attenuation of the torque oscillation at the transmission input shaft. Finally, the obtained results show the feasibility evidence for the application of weight-vibration optimized dual mass flywheels in heavy-duty truck drivetrain systems
