在未來展望方面，吾人預計除了被動式減振系統，也建議後續研究可嘗試加入主動式減振系統，預計可達到比全被動式減振系統更為優良之減振效果。 The concept of the vibration reduction via position change of the vibration absorbers was introduced in this study. A rigid body plate was taken as the main body. Each of the four corners of the main body was supported by a spring to simulate the transverse-rotate-rotate vibrations. Two point-mass shock absorbers were suspended under the body. The positions of these two absorbers could be adjusted to achieve the best vibration reduction effect. Both single-decker and double-decker vibration systems were considered in this study. Lagrange’s equation was used to obtain theoretical model of this vibration system. Both analytic and numerical results were compared to verify the impacts on system vibration from positions of the vibration absorber devices. The experimental model was also established to ensure our theoretical predictions. Both single-decker and double–decker rigid plate vibration systems with under attached absorber(s) were studied by experimental method as well. Each rigid plate degree-of-freedom’s frequency response (transverse-rotate-rotate of upper and lower deck) plots for different absorber(s) positions were analyzed. This study found that: For a single deck vibration, the case of dual-absorbers (a pair of two absorbers) attached under the forced vibration rigid plate is better than a single-absorber. For the double-decker vibration system, the case of dual-absorbers attached under each forced vibration rigid plate of the this system is better than just one pair of dual-absorbers attached under one of the rigid plates. The best positions for the dual-absorbers are one of the absorbers located at the endpoint of the quadrant which the force applied and the other one located at the cross quadrant’s endpoint. Both experimental and numerical results agree with each other very well. This confirms our results.
