Purpose: The issues to provide safety and security of wheeled vehicles transportation on open rolling stock of railways are considered. It’s been established that calculation method does not take into account fully the interaction of bracing elements with wheeled vehicles, placed in a car, as well as the absence or non-actuation of brakes (brake system faulty state). New calculated scheme is proposed for determining the loading of the elements of wheeled vehicles bracing that does not contradict existing regulatory documents. Methods: Analysis and synthesis methods, theoretical mechanics methods were applied. Results: Improved methodology for calculating the bracing of wheeled vehicles on open rolling stock is proposed that takes into account wheels unbraked state. Practical significance: The proposed methodology for calculating the bracing of unbraked wheeled vehicles on open rolling stock takes into account the parameters of friction coefficient of a wheel, the placement and estimated effort in tie-rods. The methodology was tested during wheeled vehicles transportations from Oktyabrskaya railway stations of “Russian Railways” JSC branch.
