Substantiating parameters brake system of the tractor trailer

The article discusses substantiating the parameters brake system of a tractor-trailer (TT). The section offers a comparative analysis of theoretical and experimental studies of the TT brake drive and the parameters of its elements. Based on that, ordinary differential equations were solved by the Runge - Kutta method, the first-order accuracy (Euler's method). To solve partial differential equations, we used a modified Lax - Wendroff scheme. The results were obtained using the methods described above are theoretically very consistent with the triggering time t s = 0.47 s and the experimental value 0.46 s. Thus, the studying dynamic circuits of the pneumatic drive of TT brakes showed a high converging theoretical characteristic for a typical control line of a drive with an accelerating valve with experimental data, and the error was no more than 5%.
