초록

본 연구에서는 쇽업소버 오리피스 유형별 유동해석을 하였다. 좋은 차의 기준에서 중요한 승차감을 위해서는 쇽업소버는 없어서는 안 될 존재이다. 해석 절차로서, 실제 쇽업소버의 실린더가 전진될 때의 속력을 유동 속도로 설정하여 쇽업소버의 모델 A, B, C들에 대한 유동 해석 결과들을 서로 비교하였다. 유동해석을 통해 각 모델의 오리피스 근처에서 유동흐름을 고찰하여 쇽업소버의 성능을 알아보았다. 전반적으로 모델 A가 유속이 가장 빨랐으며 유동변화 또한 가장 컸다. 모델 B가 유속이 가장 느렸으며 오리피스의 개수가 같은 모델 B, C의 유속 형상들은 비슷하였다. 본 연구를 통하여 어느 쇽업소버 오리피스 모델이 실린더 내에서의 유동을 원활히 하여 승차감을 상승시키는지를 알 수 있다. 쇽업소버 오리피스의 유형별 유동해석에 대한 본 해석 결과는 디자인 분야에 융합하여 적용될 수 있다고 보인다.

In this study, the flow analyses by type of shock absorber orifice were carried out. A shock absorber is indispensable for the ride comfort that is important at the standard of a good car. As the analysis procedure, the actual speed of the shock absorber was set as the flow rate when the cylinder was advanced. And the flow analysis results on models A, B and C of shock absorber models were compared with each other. As the examination on the flow orifice in the vicinity of each model through the analysis of flow, the performance of shock absorber were recognized. On the whole, model A had the fastest flow rate and also had the largest flow rate. Model B had the slowest flow rate and the flow rate features of models B and C with the same number of orifices were similar. Through this study, it is possible to see which shock absorber orifice model facilitates the flow inside the cylinder and increases the ride comfort. It is seen that this analysis result on the flow analyses by type of shock absorber orifice can be applied by converging with the field of design.
