A Framework for the Design of Rotating Multiple Tuned Mass Damper

Abstract

The acoustic and vibratory analysis represent an essential research axis in the automotive industry because these phenomena directly affect the appreciation of the customer when using a vehicle. Indeed, the combustion engine represents the main source of mechanical energy but it generates an acyclic torque because of the explosions. This acyclism is responsible for noise and vibration fatigue. To reduce NVH issues, a possible mean is to use a Multiple Tuned Mass Damper (MTMD) adapted to rotating machine. The purpose of this paper is to propose a framework for the design of this type of MTMD. To achieve this goal, an optimization strategy is implemented in the non-rotating and rotating case to determine the optimal distribution of the MTMD frequencies. It is based on the minimization of the elastic strain energy of the transmission chain near the torsion mode. In addition, a dedicated reduced order method is proposed to reduce the calculation costs link to the modeling of the system by the finite element method and the optimization process. However, conventional reduction order methods are not suitable for this type of problem where the shape of the modes of the main structure and the MTMD are varying according to the rotation speed. To overcome this problem, a multi-model approach is employed. Finally, the influence of the number of absorbers composing the MTMD as well as the structural damping of the absorbers and their mass on the performance of the optimal solution is presented in the non-rotating and rotating case.

Nonlinear vibration of a sliding-mode-controlled structure: Simulation and experiment

“…The first approach involves a passive method with no external energy input, resulting in limited performance. The famous Tuned Mass Damper (TMD) is a notable example of this approach [4,5]. However, the TMD is limited by its ability to damp a single frequency.…”

Master-slave synchronous control method for attenuating dual mode electromechanical transmission system torsional vibration

“…12 A novel method is the creation of an “escape way” to capture the energy of the oscillations and reduce their amplitude. This leads to multiple tuned mass dampers 13 and centrifugal pendulum dampers. 14 The most advanced method goes to modify the mechanical properties of the flywheel, such as inertia or stiffness.…”
