The Effect of Impact Absorbing System Deformation According to the Variation of Cylinder Wall Dimensions on Damping Coefficient

실린더 벽면 치수변화에 따른 변형이 충격흡수장치 감쇠계수에 미치는 영향

Many malfunctions take place in container crane spreader due to impact. So we designed a hydraulic impact absorbing equipment to absorb the impact and we studied the change of damping coefficient with respect to the variation of dimensions of oil-cylinder wall. When we design the dimension of hydraulic cylinder wall considering the displacement on the wall, the value of it over 20mm didn't affect the damping coefficient.
