Abstract

The use of slip-ring technology can solve the engineering design problems such as limited rotation angle caused by large-scale coaxial cables movement when the direction servo of the rail gun follows. This paper analyzes the failure mechanism of sliding electrical contact dynamic conduction by the slip ring in a transient high current, establish a model of temperature rise in the contact interface, the brush material and structure suitable for sliding electrical contact were determined on the basis of merit, and the dynamic test verification was completed. The research shows that under the test conditions with a running speed of 30 m per second, the brush can carry a maximum current density of 1800 A per square centimeter, and the surface of the brush is in good condition. The test results provides a technical way for the design of the directional slip-ring of the rail gun.
