specific Embodiment 1

[0062] image 3 Shown is the form of two C-shaped magnetic circuits oppositely butted together, in which there are three parts A, B and C where electromagnetic coils can be placed. The coils of the three parts can be freely combined according to the specific situation, so as to meet the restrictions of the external installation environment and so on. Of course, the electromagnetic coils at the left and right sides A and B can be respectively connected into a whole, so that the space can be fully utilized. Wherein, the openings of the two C-shaped magnetic circuits face each other and share a pair of joints.

specific Embodiment 2

[0064] Figure 4 , Figure 5 , Figure 6 Two C-type drivers are connected together in a vertical manner, and the dotted line part is the conduction of the magnetic circuit. This arrangement takes into account the limitation of the special space installation position. Coils at D, E, F can be selectively arranged.

specific Embodiment 3

[0066] Coil 1 is not limited to Figure 7 , Figure 8 , Figure 9 shown, it can also be located at Figure 7 , Figure 8 The position shown by the dotted line in the middle, or a random combination thereof. Here, the magnetic circuit 2 is equivalent to being composed of three C-type drivers. The functions of other parts can refer to figure 1 structure and function.

Abstract

The invention provides a torsional vibration test system and a combined device. The torsional vibration test system comprises coils, a magnetic conductive circuit, joints, magnetic bodies and a rotary shaft. The coils are wound on the magnetic conductive circuit; openings are formed in the magnetic conductive circuit to form two joints, the two joints of the magnetic conductive circuit are respectively connected with the two connectors in a connector pair; the magnetic bodies are connected with the rotary shaft and are positioned between the two connectors. The torsional vibration test system and the combined device has the advantages that external rotary components can be directly driven by the rotary shaft to output torsion without speed reducers, and the torsional vibration test system and the combined device are high in mechanical transmission efficiency; the torsional vibration test system and the combined device without middle transmission links are fast in response, and noise at fixed frequencies when teeth of the speed reducers mesh with one another can be prevented; only the frequencies of power-on currents of the coils need to be changed, so that torsional frequencies of shafts can be changed, and the torsional vibration test system and the combined device are good in low-frequency and high-frequency performance; external magnetic shielding components can be omitted during driving, and accordingly the structures of the torsional vibration test system and the combined device can be simplified; the torsional vibration test system and the combined device are flexible in arrangement and high in space adaptability; magnetic circuit components are in changeable shapes.

Description

technical field [0001] The present invention relates to the field of torsional vibration testing platform, material torsional characteristic testing technology and electromagnetic permanent magnet direct drive technology, in particular to a torsional vibration testing system device and a combined device thereof. Background technique [0002] The torsional vibration test system is mainly used for the application of torsional vibration excitation, to test the functional parameters of products under torsional vibration state and the endurance performance of materials under torsional excitation. Existing vibrating tables and material performance testing devices mainly apply excitation in three translational directions to test the functional properties of products and the tensile and compressive properties of materials, which can only meet general application requirements. For some special application fields and occasions, the torsional performance of products and materials must ...
