DEVICE FOR DYNAMIC TESTS OF ELECTRIC RAIL VEHICLE CURRENT COLLECTORS

摘要

FIELD: electrified transport.;SUBSTANCE: invention relates to laboratory dynamic testing of current collectors of underground and monorail vehicles. proposed tester includes current wire vibration simulator on which striker is installed connected with translational displacement drive and interacting with current collector. Striker travel speed regulator is provided whose input is connected with output of pickup of simulator vertical vibration frequency. Horizontal part of striker in direction of its movement is made of two sections with clearance, one of sections being furnished with device for adjusting size of clearance and position of working surface in height.;EFFECT: enlarged functional capabilities of device by simulating passing of expansion gaps by current collector.;1 dwg
