1.Purpose: TMDs, also known as dynamic vibration absorbers, are widely used to suppress vibrations in engineering structures subjected to external loads.
2.Components: A classical TMD typically comprises a mass, spring, and damper. These components are attached to the primary vibrating system to achieve desired frequency-response behavior.
3.Equal-Peak Method: The response curve of a harmonically excited single-degree-of-freedom (DOF) primary system with a TMD passes through two fixed points. The equal-peak method helps findapproximate optimal values for the stiffness and damping of the absorber.
4.Optimal Design: Recent research has provided exact closed-form solutions for the optimal stiffness and damping of TMDs.
