FUNCTIONAL-COST ANALYSIS OF THE ANTI-LOCK BRAKING SYSTEM (ABS) OF CARS

Abstract

Functional-cost analysis is a method that has a heuristic nature and is used to identify opportunities to reduce costs and improve the quality of an object, which is considered as a system with a functional orientation at all stages of its life cycle. This article considers the application of functional cost analysis for the anti-lock braking system of cars. As part of this study, a functional model of the car's anti-lock braking system was developed and its functions were classified. The classification of functions within the framework of the functional model of the anti-lock braking system of cars was also carried out. To determine the utility coefficients of this system, a matrix of priorities was built using a known calculation method. When designing technical or production systems, the general cost criterion takes into account costs at all stages of the system's life cycle. For this evaluation, a matrix of anti-lock braking system of cars was created, which allows to compensate the cost factor. The results of the study are the construction of a diagram of the utility of the functions of the anti-lock braking system of cars, a diagram of the location of the system functions taking into account the utility factor, a functional cost diagram of the system, a diagram of the costs of the system functions, a diagram of the location of the system functions taking into account the cost factor, a diagram of the value of the indicator of the functional cost of the system functions, and diagrams of the location of system functions with the calculation of the functional cost indicator. Based on the analysis of this diagram, the functions of the anti-lock braking system of the car were determined, which have a positive functional value indicator and the highest rating among the functional functions. operations or functions that have the highest functional value indicator and rank.
