전달행렬법을 이용한 집중 질량 진자형 원심진자 흡진기 검토

초록

The transfer matrix for a simple centrifugal pendulum absorber (CPA) is defined using the vector-type four-pole parameter method. The matrix is validated by comparing the angular accelerance of the absorber obtained by the transfer-matrix method (TMM) adopting derived matrix with the angular accelerance from the traditional method using inertia, stiffness, and damping matrices. Then, TMM is used to calculate the angular displacement transmissibility of a base excited 2-degree-of-freedom system. The optimal configuration of the CPA is investigated using the transfer matrix derived in the first step. The displacement transmissibility of the system modified by the CPA is compared with that of the original system to determine the effect of the CPA. Finally, the displacement transmissibility of a system modified by the CPA is compared with that of the system using a classical dynamic absorber. The results indicate that the transfer matrix introduced in this study can be utilized to investigate the performance of the given CPA and determine the optimal configuration of the CPA for the given requirements.
