Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric machines, and relates to a test support of a suspended electric machine, in particular to a suspended electric machine test device capable of multi-degree-of-freedom adjustment. BACKGROUND

[0002] Electric machines are usually installed in a suspended manner. With the development of domestic rail transit, especially the increasing number of subway lines, the interface size requirements of electric machines of various projects are different, and according to incomplete statistics, there are more than 40 kinds.

[0003] After the first batch of electric machines are produced, type tests of electric machines and ground system joint debugging tests need to be performed. The test is an important link for verifying whether the design of the electric machine meets the requirements. The type test of the electric machine needs one electric machine and one test support (connecting and reliably fixing the electric machine and the load). The ground system joint debugging test needs four electric machines and four test supports (connecting and reliably fixing the electric machine and the load). Usually, the type test of the electric machine and the ground system joint debugging test adopt different test benches, and due to the difference in the center height of the load bench, different test supports need to be configured, which leads to further increase in the types of test supports.

[0004] The test support needs to meet the requirements of different interface sizes of the electric machine and the center height of the test load bench. Common interface types of the suspended electric machine are shown in Figure 1 The mechanical installation interface is located on the upper and lower hangers. As shown in Figure 2 , Figure 3 and Figure 4 , the size of the upper hanger interface includes the height size H1, the horizontal size L1 and the axial size B1, and the size of the lower hanger interface includes the height size H2, the horizontal size L2 and the axial size B2.

[0005] The existing technology one, the test support is limited by the installation interface of the upper and lower hangers of the electric machine and the center height limit of the test load bench, and any change in the size leads to the fact that the test support cannot be commonly used, the types of test supports are various, not easy to manage, the manufacturing cost is high, and the production cycle is long.
