In the paper, the author applies the methodology of multi-objective optimal design of engineering systems to consider a problem on the weight-vibration Pareto optimization of a dual mass flywheel. The aim of the investigation is to study the feasibility of the flywheel application in heavy-duty truck powertrains. The results obtained show that the solution of the optimization problem under consideration exists; the absorber mass, stiffness and damping parameters, optimized in the operating engine speed range of 600-2000 rpm, exist and provide the best attenuation of torque oscillations of the input transmission shaft. Finally, the results show the feasibility of application of a weight-vibration optimized dual mass flywheel in the drivetrain systems of heavy-duty trucks.
