연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

Two No Spin Differential(NSD) models were benchmarked for a project of Dual-Use Technology. The Axiomatic approach is utilized to evaluate the designs of the models. The Independence Axiom is satisfied at the top level of design but not at the second level, which implies the design exhibits coupling...

  • (3) The greater the tooth-form width of the center cam is, the smoother the NSD operates. This helps a vehicle to get out of a swamp quickly through prompt NSD operation.
  • · DP12 - Minimum steering time: keeping steering time to minimum greatly affects turning speed.
  • · DP13 - Holdout-ring shape: the profile of tooth form affects contact strength between the center cam and the spider.
  • · DP14 - Number of holdout-ring teeth: tooth number synchronization vis-a-vis the center cam greatly improves receptiveness, thus effecting promptness of response.
  • · DP2 - Tooth-form profile: a design parameter greatly affecting noise generated during NSD engagement or separation.
  • · DP21 - Retainer structure: putting together the spring retainer and the side gear greatly simplifies overall structure.
  • · DP22 -Cam tooth surface processing: the roughness grade of the center cam's tooth surface greatly affects the level of noise.
  • · DP24 - Center cam tooth form: the smooth tooth form of the center cam greatly affects noise reduction by minimizing friction and interference.
  • · DP31 - Movement time: a vehicle should move as quick­ly as possible to get out of a swamp. And speedy response greatly affects speedy movement.
  • · DP32 - Center cam structure: the form and width of the center cam do affect smooth and safe operation of NSD greatly.
  • · FR1 - Improved steerability: When cornering or running on an uneven surface, the number of spins for wheels on one side must differ from that for the wheels on the other side. So it is important to improve steerability so as to minimize the turn radius by preventing outer wheels from skidding.
  • · FR11 - Minimum turn radius: It is important to make a turn within the smallest radius possible during separation of NSD.
  • · FR13 - Smooth contact: Smooth contact between the center cam and the holdout ring during turning improves the steerability.
  • · FR2 - Reduced noise: Internal NSD noise must be reduced to ensure quiet and pleasant driving.
  • · FR31 - Speedy movement: NSD activated by low RPM should escape from a swamp quickly.
  • · DP23 - Clutch tooth form: the tooth form of clutch has a significant effect on reducing noise generated while interacting with the center cam beside its smooth profile makes it easy to link.
