Bistable mechanisms, characterized by their ability to maintain two distinct stable states under external stimuli, offer a versatile solution engineering challenges, particularly in vibration suppression systems. While tuned mass dampers (TMDs) effectively mitigate vibrations at specific frequencies, efficacy falls short across broader spectrum. This work proposes enhanced adaptability for passive reduction without dependence on complex control systems or power sources integrating bistable mechanisms into TMD A mechanism is designed based numerical simulations and 3D‐printed via fused filament fabrication. The provides more adaptive characteristics displacing the flexible link. Following experimental testing, optimized design has been determined. Then, chain of introduced achieve desired displacement carrying payload. stroke length test customized reduce system carefully optimizing geometric configurations mechanisms.
