Rover wheel's mobility depends on soil's condition and wheel's design. The purpose of this study is to evaluate the effect of soil conditions, which are Jumunjin sand and Korean lunar soil simulant (KLS-1), on wheel's motion performance. The experiments were performed by using a single wheel testbed...

차량 휠의 거동 성능은 어떤 능력을 통해 평가되는가? | 일반적으로 차량 휠의 거동 성능은 운동 저항력을 극복하고 견인력을 발현할 수 있는 능력으로 평가된다(Wong, 2010). 또한 변형이 심한 흙에서의 차량 주행은 휠과 지반의 상호작용에 의해 발생하는 추진력에 의해 이루어진다. | |
루노호트의 제원은? | 러시아, 미국, 중국에서 각각 루노호트(Lunokhod), LRV (Lunar Rover Vehicle), 위투(Yutu)라는 이름의 탐사 로버를 이용하여 달탐사 프로젝트를 수행하였다. 루노호트의 총 중량은 2.7kg이고, 휠의 직경과 폭은 각각 51cm, 20cm이다. 휠과 그라우저의 재질은 티타늄, 스파이크의 재질은 강철로 제작되었다. | |
러시아, 미국, 중국의 달탐사 로버는 각각 무엇인가? | 우주개발 선진국에서는 서로 다른 달 탐사 임무를 수행하기 위하여 다양한 종류의 달탐사 로버가 개발되어 사용되고 있다. 러시아, 미국, 중국에서 각각 루노호트(Lunokhod), LRV (Lunar Rover Vehicle), 위투(Yutu)라는 이름의 탐사 로버를 이용하여 달탐사 프로젝트를 수행하였다. 루노호트의 총 중량은 2. |
