METHOD OF SELECTING RETARDER FOR MOTOR-AND-TRACTOR ROLLING STOCK
Abstract
A method of selecting secondary braking systems for vehicles and wheeled tractor trucks involved in agricultural transportation is proposed based on expert judgment of qualitative properties of the mentioned systems of different types. Comparison of the qualitative properties, which, in fact, are requirements to secondary braking systems, first of all addressed to the preference of selecting one or another retarder. Then, based on expert quantitative judgments, the numerical characteristic of different groups of the mentioned requirements has been determined. By determining the sum of estimates of all requirement groups with the help of the mathematical model presented, the final selection, which is the quantitative estimate playing a role of that for the type of retarder, has been made. Using the balance diagram of braking power, the braking power of the selected secondary braking system for vehicle or wheeled tractor truck has been determined during braking with constant speed on downhill with the slope of 7% and length of 6 km. Taking into account that data on braking power balance constituents do not exist in scientific-technical literature, the mentioned constituents are presented in detail in the article.
