Description

technical field [0001] The invention relates to the technical field of friction test equipment, in particular to a friction test device with controllable ambient temperature and humidity. Background technique [0002] Friction comes from relative motion or the interaction between surfaces with relative motion tendencies. It exists widely in nature and human production and life. On the one hand, for example, the normal work of clutches or the movement of animals. Unable to move an inch, friction is a daily requirement in this case. On the other hand, the existence of friction means the loss of energy. For example, the friction between the drive shaft and the hub of a car will cause the loss of kinetic energy output by the engine. More importantly, in the field of tribology, tribology has the characteristics of frontier subject, wide applicability and multidisciplinary interdisciplinary, and its subject basis involves the fields of mechanics, material science, manufacturing s...

AI Technical Summary

Problems solved by technology

As we all know, in most solid friction pairs, the temperature and humidity of the environment will have a greater impact on the measurement of friction, especially when the humidity in the environment is relatively high, or when the temperature changes greatly, water vapor will condense On the surface of the friction pair, even small water droplets are formed to lubricate, thus affecting the accurate measurement of friction force

However, the existing friction testing devices are still insufficient in this respect, it is difficult to effectively control the temperature and humidity in the test environment at the same time, so it is difficult to overcome the influence of ambient temperature and humidity

Moreover, using existing equipment to quantitatively study the effects of temperature and humidity changes (especially high temperature, high humidity, and low temperature below 0°C) on friction is also facing great difficulties
