摘要
FIELD: transport mechanical engineering. SUBSTANCE: active zone of bed has two inclined sections with railway tracks placed in symmetry which provides for opposing traffic of cars for their collision in central horizontal part. Tested cars are set at starting bed position. Bed is fitted with accelerator manufactured in the form of set of pneumatic cylinders integrated into one power unit to impart cars with initial acceleration. Rods of cylinders are hinged to plate on which body of automatic coupler to transmit initial pulse of force is anchored fast. EFFECT: improved authenticity of service life tests. 4 dwg
