강체성 PTH에 삽입되는 CPF 핀의 접촉응력에 대한 유한요소해석

Finite Element Analysis for the Contact Stress of CPF Pin Inserted into the Rigid PTH

The contact stress characteristics of the domestic CPF pin when inserted into the rigid PTH was analyzed using the finite element method. The model geometry was based on the shape of the existing pin and the two different PTH diameters were used in the analysis. The stress distributions with respect to the friction coefficients were compared and the stress variations of the compliant part of the pin, which have an influence on the performance, were displayed with the time and the arc length on complete connection.
