REATION OF A UNIVERSAL MEASUREMENT COMPLEX FOR ROAD TESTS OF WHEELED VEHICLES
DOI: 10.33868/0365-8392-2023-2-274-12-20
Abstract. The results of studies related to the development of a universal measuring complex for road testing of wheeled vehicles (hereinafter referred to as the complex) are presented. The substantiation of the list of parameters measured by the complex and their metrological characteristics has been carried out, and the general requirements for the complex have been formulated; the basic principles of building special software included in the complex are given. The issues of calibration of the measuring systems of the complex are con-sidered in detail and the methods used for this, including features of the calibration method of the deceleration/ acceleration measurement system, are described. The description and technical characteristics of the developed complex are presented, as well as the results of its calibration and trial operation. On the basis of experimental studies, the expediency of using a two-stage method of calibrating path, speed and decelera-tion/acceleration measurement systems has been confirmed. As an example, the results of testing a vehicle for compliance with the requirements of UN Regulation No. 13, obtained using the complex, are shown, and the main software windows during these tests are described in detail.
Keywords: wheeled vehicle testing, UN Regulations, measurement system, calibration, sensor, software, measuring complex, error, parameter, road test, speed, path, deceleration.
