In this paper, we analyze the effects such as velocity and stroke on a one-way damper for doors. Experiments were conducted to acquire the data for the analysis. The experiments were done using a one-way damper tester developed in this study . The damping force for the stroke was measured by the damper tester. The damper used in this study has different stroke and damping force. We analyzed the data acquired in the one-way damper testing machine. The analysis results will be useful in improving the performance of the door damper and testing machine. To ensure that a one-way damper design is effective, some shapes are modeled by a 3D CAD program, analyzed using a flow analysis program, and the results are described in this paper.
