Vibration and rotation comprehensive experiment device

Abstract

The invention discloses a vibration and rotation comprehensive experiment device, which comprises a supporting table and a supporting frame vertically installed on the right side of the surface of thesupporting table, wherein at least two working boxes are vertically installed on the surface of the supporting table, a working table is transversely installed at the top ends of the working boxes, the surface of the working table is covered with a protection box, thus a to-be-tested part is protected and fixed through the protection box and is subjected to a vibration test, a rotating shaft is vertically installed at the top end of the exterior of the protection box, the rotating shaft drives the protection box to rotate, and then a rotation test is carried out. Compared with the prior art,the vibration and rotation comprehensive experiment device has the beneficial effects that two-point vibration excitation and rotation excitation of the test piece (a bearing of a locomotive axle) arerealized, the actual working condition of the bearing is simulated more truly, the failure mode of the test piece (the bearing of the locomotive axle) can be found out more truly, and the reliabilityof the test piece (the bearing of the locomotive axle) is improved.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a vibration-rotation comprehensive experimental device. Background technique [0002] At present, the bearing test for the locomotive axle is mainly a single-point vibration mode, and the transmission shaft and bearing are installed on a large single-axis vibration table to vibrate through the design tooling. Moreover, the rotation test is done separately from the vibration test and is not combined together. With the development of the locomotive industry, it is gradually found that the current locomotive bearing test cannot meet the actual needs, because the failure modes of the bearings account for a relatively high proportion during the operation of the locomotive. It is very likely that the current locomotive bearing test is difficult to truly simulate the actual working state of the bearing due to the under-testing of the locomotive bearing. Therefore, a comprehensive ...

Problems solved by technology

With the development of the locomotive industry, it is gradually discovered that the current locomotive bearing test cannot meet the actual needs, because the failure mode of the bearing during the locomotive operation is relatively high.

It is very likely that the current locomotive bearing test is difficult to truly simulate the actual working state of the bearing due to the under-testing of the locomotive bearing. Therefore, a comprehensive vibration and rotation experimental device is proposed.
