The stand modernization for stabilizing the input parameter and testing of bushings’ work quality of cars’ suspenders

The system of diagnosing and tests of car units consists of the interface and personal computers, united in one network that facilitates the procedure of diagnosing and reduces time spent for diagnosing. However, most cars have such elements (details) that it is impossible to determine their technical condition with the use of diagnostic testers (OBD II) and diagnostic stands, due to its location on the vehicle and the specifics of its use and purpose. Nevertheless, maintaining such items in good technical condition during the operation period is essential to reduce accidents and increase vehicle active safety. The diagnostics ’ methods of suspenders are continuously being improved. However, the existing methods and stands do not allow revealing all the faults of suspenders due to the limited functionality of the existing stands. The article considers the modernization of the diagnostic stand of cars’ suspenders. The new structure of the experimental stand is defined in the work. Scientific - test complex will be used for the diagnosis of cars’ suspenders for the detection of faults at an early stage of their occurrence. This will allow monitoring the technical condition during the entire period of vehicle operation. New tests of bushings and their analysis have been held according to the program.
