Fulfilling the requirements of the EU Directive 2015/68 in the area of braking for agricultural trailers depends on the proper
selection of individual components of the braking system. This paper describes the requirements regarding braking performance
and distribution of brake forces in agricultural trailers in R3 and R4 categories. On this basis, a methodology for calculating
the optimal linear distribution of brake forces, characteristic for agricultural trailers with pneumatic braking systems, has been
developed. The examples of calculation of an optimal distribution of brake forces for a two- and three-axle trailer with a tandem
suspension system of the rear axle assembly have been provided. The optimization algorithm with the Monte Carlo method has
been described, based on which a computer program was developed to select a linear distribution of brake forces in a three-axle
trailer with ‘walking beam’ and ‘bogie’ suspensions. The presented calculations can be used in the design process to select the
parameters of wheel braking mechanisms and then the characteristics of the pneumatic valves of the braking system.
