Annotation:
this article cites information on the effect of air temperature on rail
plets and the distribution of stresses caused by it.
Keywords:
Rail plate, air temperature, optimum temperature.
Today we cannot imagine our day without developments. Our century is a
century of development. Rail transport is continuously developing
as all industries
have developed during this period. In particular, in order to improve the comfort of
the Rail Road and reduce the labor costs of road workers serving on the road, various
updated structures have been used on railway overhead structures. As one of these,
welded rails in portable and stationary methods are
widely used in rail welding
enterprises from 150 m to 2000 m instead of standard 25 m long rails. As each
novelty has its own advantages and disadvantages, there
are also disadvantages to
using rail plates on the road. Below we will dwell on the effect of air temperature
when we use rail plets.
In meteorology, air temperature is understood as the temperature obtained in a
metrological cabin, which protects a thermometer at a height of 2 m from the
radiation of sunlight directly from the Earth’s surface and surrounding details. In this
cabin, quick, extreme, minimum, maximum temperature indicators can be obtained.
For
standard observations, liquid thermometers are used; for quick temperature
determination, and for measuring the
maximum temperature-Mercury, and at low
temperatures-alcohol. Thermographs are used to continuously record temperature
changes.[1]
