Embodiment Construction

[0030] combine Figure 1 to Figure 4 As shown, the overall hanging string vibration fatigue testing machine of the present invention comprises a frame and a main frame positioned at the frame. The frame includes a main frame 22 and a drag frame 23 fixed on the top of the main frame 22. The main frame includes a mounting base plate 24, a fixed A driving device on the drag frame 23, and six parallel test devices with the same structure.

[0031] combine figure 1 and figure 2 As shown, the driving device includes a variable frequency motor 1 and a reducer 2 . Each test device includes an eccentric wheel 4, an eccentric wheel fixing flange 5, a movement mode conversion mechanism and a length adjustment device. The output shaft of the reducer 2, that is, the transmission main shaft 3 is a hexagonal transmission main shaft. Three hexagonal holes matching the transmission main shaft 3 are respectively opened on the eccentric wheel 4 at 35mm, 60mm, and 75mm from the center of the ...

Abstract

The invention relates to an integral dropper vibration fatigue tester, comprising a rack and a body in the rack, wherein the rack comprises a main rack and a dragging rack fixed above the main rack; the body comprises an installation base plate, a driving device fixed to the dragging rack and a plurality of test units fixed between the dragging rack and the installation base plate. The integral dropper vibration fatigue tester can simulate running condition of the integral dropper and realize continuous simulation of vibration test.

Description

technical field [0001] The invention relates to a testing machine, in particular to a testing machine for vibration fatigue testing of integral suspension strings. Background technique [0002] The overall suspension string is the most used part of the catenary, and an average of 7m is installed on the high-speed rail catenary. It is used to evenly suspend the contact line with horizontal tension on the catenary cable, so that the height of the contact line to the rail plane along the line direction is consistent, and it creates conditions for the smooth flow of the high-speed locomotive pantograph. [0003] The overall suspension strings used in my country's high-speed railway catenary, and a full set of production technology such as material selection, manufacturing process, crimping method, on-site installation and commissioning, etc. are basically the same as those in Germany. However, due to the differences in the catenary systems of the two countries, the operation pr...
