프레스 기계의 불평형 관성력 계산과 진동 해석

In this study, unbalanced inertia force is calculated through mathematical modeling of a press machine, and floor transfer force excited by the inertia force is analyzed. The method of calculating the unbalanced inertia force is verified by comparing the results of 1 degree-of-freedom forced vibration analysis with those of multi-body dynamics model. The unbalanced inertia force has maximum and minimum values ​​in the return stroke and did not overlap with the processing impact force. The floor transfer force is almost equal to the unbalanced inertial force such that the unbalanced inertial force is transmitted to the transferring force of the support as it is. By changing the design position of the link, it is found that the transfer force can be reduced more effectively than the stiffness or damping of the support. KCI Citation Count: 0
