To expand the airfoil database and realize reverse digital design, this paper proposes a new sectional expression function of wind turbine based on Joukowski transformation derives equation for novel airfoil. Compared with existing function, can adjust parameter values to control relative thickness, thickness position, camber, camber position Taking common (NACA63-212) as an example, is fitted ...

In the field of inner-city cargo transportation, solutions such as electrified trailers are increasingly being used. To provide an intelligent drivetrain control system that improves driving dynamics and enables safety, it is necessary to know characteristics trailer system. This includes behavior tires. Existing investigations bicycle tires focus on camber-angle-dependent models. However, in m...

Purpose – The purpose of this paper is to evaluate the locomotion performance of all-terrain rovers employing rocker-type suspension system. Design/methodology/approach – In this paper, a robot with advanced mobility features is presented and its locomotion performance is evaluated, following an analytical approach via extensive simulations. The vehicle features an independently controlled four...

Unlike hinged flaps (for example, ailerons, elevators, and rudders), camber morphing devices vary distribution in a smooth continuous way, resulting aerodynamic efficiency improvements due to the absence of sharp changes airfoil camber. One such concept, Fish Bone Active Camber (FishBAC) device, has shown significant benefits when compared flap. In this work, quasi-two-dimensional wind-tunnel t...

Friction material, as the main component in a bearing support, allows frictionless behavior between two connected structures. Previous studies on friction material considered polytetrafluoroethylene (PTFE) and attempted to analyze resulting balance. However, aging PTFE loses its performances, because is crushed, causing it tear, or lubricant removed. The performances of should thus be maintaine...
