Abstract

The front bumper of bobsleigh is mounted to alleviate the impact, but the air resistance to the bobsleigh depends on the body shape positioned in front. This study was conducted the flow analyses about three kinds of bobsleigh configurations. Models B and C with the sharp type of the front can reduce the air resistance than model A with the round type of the front. And the type that the back of the bumper narrows can generate a flow smoother than the one widening. It is thought that the results of this study can be devoted at ensuring the body design to reduce the flow resistance most at bobsleigh. As the design data with the durability of bobsleigh obtained on the basis of this study result are utilized, the esthetic sense can be shown by being grafted onto the machine or structure at real life.

충격을 완화시키기 위해 봅슬레이의 프론트 범퍼가 장착되지만, 봅슬레이에 대한 공기 저항은 앞에 위치한 몸체의 형태에 따라 달라진다. 본 연구에서는 봅슬레이의 세 가지 형상에 대한 유동 해석을 수행하였으며, 압력을 적게 받게 되는 모델 B, C인 앞이 뾰족한 형태가 앞이 둥근 모델인 모델 A보다 공기 저항을 줄일 수 있고 범퍼 뒤 쪽이 좁아지는 형태가 넓어지는 형보다 좀 더 매끄러운 유동 흐름이 될 수 있다. 본 연구 결과는 봅슬레이에서의 유동 저항을 가장 줄일 수 있는 몸체의 설계를 확보하는 데 기여할 수 있다고 사료된다. 본 연구결과를 토대로 얻은 봅슬레이의 내구성 있는 설계데이터를 활용함으로서 실생활에서의 기계나 구조물에 융합하여 그 미적 감각을 나타낼 수 있다.
