The concept of using tuned mass dampers and absorbers to address undesirable vibration responses in vehicles is not new. However, there are several design issues that cause the vibration control performance of real life tuned dampers to be significantly less than that predicted by simple 2-DOF theory.
In this paper, the authors will review tuned damper design theory. Practical issues regarding the use of real life elastomers as spring elements are reviewed, including temperature sensitivity, material damping and nonlinearity. Various elastomers are compared for their effectiveness and applicability to the typical automotive environment. Rules of thumb for tuned damper design are discussed including locations for placement of dampers in automotive structures, tuning for temperature variations, determining the needed mass, and measurements and simulations that can greatly improve the success and timing for tuned damper design.
