Substantiating parameters brake system of the tractor trailer

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