Tension testing device and method for eddy current brake

Abstract

The invention discloses a tension testing device and a tension testing method for an eddy current brake. The tension testing device comprises a base and a load applying assembly, a tested piece is placed on the base; the load applying assembly comprises a first supporting frame, a second supporting frame and a load applying piece. The first supporting frame is arranged on the base, a first accommodating space is formed between the top end of the first supporting frame and the base, and a tested piece is arranged in the first accommodating space; the bottom end part of the second support frame is connected with the tested piece, the top end part of the second support frame is positioned above the top end part of the first support frame, and a second accommodating space is formed between the top end part of the second support frame and the top end part of the first support frame; the load applying piece is located in the second containing space and fixedly arranged at the top end of the first supporting frame, the load output end of the load applying piece is connected with the top end of the second supporting frame, and the data collecting assembly is connected with the load applying piece. The technical problem of high and low temperature tension test requirements of the Y-direction connection subassembly of the eddy current brake in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a tensile test device and a test method for an eddy current brake. Background technique [0002] The eddy current brake is suitable for the braking requirements of high-speed rail vehicles running at high speed. The Y-direction (vehicle transverse) connection part is an important part of the eddy current brake body. When the braking effect occurs, the Y-direction connection part can realize the Y The transmission to the electromagnetic attraction provides braking force to the train while releasing the X-direction (vehicle longitudinal) degree of freedom. [0003] In the prior art, in order to ensure the gap between the magnetic pole and the lateral track plate, it is usually necessary to apply a certain preload to the rubber spring installed in the Y-direction connecting part during assembly. In order to make the preload installed on the connecting part along the Y d...
