Frictional resistance on ice and snow was examined in terms of current frictional theories. It was concluded that a liquidlike film of some type exists or is formed on the ice surface. The basic mechanism forming this film is either the frictional heating mechanism suggested by Bowden, or is ...
Definitions Ice is the solid state of water, commonly occurring as a polycrystalline material with a hexagonal crystal structure (Ice Ih). Snow consists of ice particles that are formed by deposition of water vapor on ice-forming nuclei. It precipitates as granular material, though usually as agg...
The nature of snow and the ever-changing environment makes measuring friction on snow and ice challenging. Additionally, due to the low friction involved, the equipment used must exhibit high sensitivity. Previous investigations of ski-snow friction have ranged from small-scale model experiments perfor...

Bobsleigh runners are a critical factor for success in bobsleigh races. It is very important to use runners which generate a minimum frictional loss in contact with ice. As other studies show, the pressure greatly influences the coefficient of friction b
Internal friction of ice The present status of studies on the internal friction of ice (Ih) is reviewed from the point of view of lattice imperfections. The internal fri... Mitsugu,OGURO - 《Journal of the Japanese Society of Snow & Ice》 被引量: 0发表: 1979年 Internal Friction of Simp...
While sliders must be designed for use over a narrow range of snow and weather conditions, polyethylene bases can be structured and waxed to broaden that range. The important processes operate not at the air temperature, but at the ski base temperature, which is highly dependent on such things...
other. The constant of proportionality varies depending on the surfaces which are in contact. For example, you might expect smaller friction when two "slick" surfaces – such as a block of ice on a frozen lake – are in contact, and larger friction when two "rough" surfaces are in ...
Rolling frictioninvolves wheels or balls moving over a surface. In this process, a rough material engages with the wheel or ball, preventing slipping or sliding. For instance, when a car tire rotates on ice or snow, friction stops it from gripping the ground, allowing it to continue rotating...
In which by under the ice accretion, the snow, the ponding road surface environment the accident formation rate is highest, this possibly is because the snow and ice road surface coefficient of adhesion is small, the wheel slips controls and so on the reason results with difficulty. ...
