EXPERIMENTAL DETERMINATION OF PHYSICAL AND MECHANICAL CHARACTERISTICS OF THE VEHICLE
Abstract
Due to the penetration of moisture and harmful impurities from the air the conditions for the development of electrochemical corrosion appear on the surface of the cars.
The article discusses the experimental results obtained by students in the study of the surface of the car for the presence of corrosion damage. Methods of non-destructive testing of corrosion state of the surface are well known: ultrasonic flaw detection, acoustic emission, radiography, thermography, electrical resistance method, etc.
Students got acquainted with the method of recognition of sub-film corrosion on the surface of the car with the help of a thermal imager, whose work is based on obtaining a thermal image in the infrared region of the spectrum without direct contact with the metal sample under study. The method allows to quantify the surface area of the metal sample exposed to corrosion.
The article also presents the calculations of the spring suspension of the car, based on knowledge of the laws of physics, namely, Hooke's law.About the Authors
