Abstract

The invention relates to a vibrating table short circuit ring cooling structure and a preparation method thereof. The short circuit ring cooling structure comprises a short circuit ring arranged on a magnetic cylinder and / or central magnetic pole, wherein the inner wall of the magnetic cylinder or the outer wall of the central magnetic pole is provided with at least one annular groove; the annular groove is communicated with at least two deep holes which are axially formed in the magnetic cylinder or the central magnetic pole; at least one deep hole is also communicated with a cooling water supply device to form a water inlet passage; the rest deep holes are communicated with the exterior of the magnetic cylinder or the central magnetic pole to form a water discharge passage; and the short circuit ring covers the annular groove and is hermetically and circularly connected with the inner wall of the magnetic cylinder or the outer wall of the central magnetic pole. The vibrating table short circuit ring cooling structure can efficiently cool the short circuit ring and has the advantages of high sealing property, no threat of leakage of the cooling liquid, simple machining process and low cost.

Description

technical field [0001] The invention relates to an electrodynamic vibration test equipment and a construction method thereof in the field of vibration test technology, in particular to a short-circuit ring cooling structure of a vibration table and a preparation method thereof. Background technique [0002] In commonly used electric vibrating tables, short-circuit copper rings are generally arranged on the center magnetic pole and the magnetic cylinder. Its function is to change the equivalent impedance of the magnetic circuit system, increase the input current and increase the output electromotive force, and can also be used as a compensation coil to offset or weaken the dynamic vibration. The constant and angular frequency components of the electromotive force generated by the circular motion increase the amplitude and reduce the distortion. But at the same time, there will be a large eddy current in the short-circuit copper ring, and a large amount of heat will be generat...
