Assessing the level of effort, resulting in inhibition of only the brain connected to the train the train (without synchronization system)
Long-acting force between the coupled trains should not exceed 50 ton in the presence of the tail section of the first and second trains of empty head, slightly loaded (up to 10 tonnes per axle) cars or trolleys for passenger cars in terms of their descent, and 100 ton truck loaded with cars.
Between the mass of the train braked brain Qg (t), a mass suspended on him netormozimogo train (or two trains netormozimyh) Qx (t), force F (n) in the automatic coupler, the calculated braking ratio p cerebral trains and friction pads cr.
Short-term dynamic forces acting in excess of established standards, cause the destruction of rolling stock (mainly breaking pulling faces), long-acting - the gathering of empty and loaded wagons weak.
