FIELD: testing equipment. SUBSTANCE: bed is meant for investigation of systems of traction and electromagnetic suspension of contactless locomotive underframes. Simulation of motion of inductor relative to track is provided with movement of beam simulating track structure with specified velocity. This movement occurs within limits of thread length of lead screw. When nut approaches finish of thread of lead screw one of directing rollers presses against limit switch which breaks power supply circuit of electric motor or reverses the motion. EFFECT: enhanced authenticity of testing. 3 dwg
