摘要：
This paper describes a flexure-based platform with tunable dynamics that is used for milling stability experiments. Damping is added to a parallelogram, leaf-type flexure by incorporating an eddy current damper. Using this flexure/damper combination, the platform dynamics can be selected (tuned) at the design stage to match the desired experimental conditions. An increase in the dimensionless damping ratio of over 200% is demonstrated through the addition of the eddy current damper. The design analysis is detailed and experimental results are presented for modal testing and milling stability trials. (C) 2016 Elsevier Inc. All rights reserved.
