FIELD: engines and pumps. ^ SUBSTANCE: invention relates to machine building and can be used for vibration-resistance tests. Proposed device consists of base supporting, via pedestal, rail stacks and table supporting aforesaid rail stacks at their center. Electromagnets are fixed below aforesaid tables to make them oscillate. Tested motor attachments are also arranged on aforesaid tables and represent, on one side, a port fixed on the base for motor suspension bracket to be hinged thereto, and on the other side, posts mounted on the said table and furnished with rectangular-section beam supporting two inserts with sizes identical to those of traction motor support bearings. Note here that insert inside features rectangular-section openings. Note also that the gap between inserts and beam support surfaces is filled with technical felt. ^ EFFECT: vibration-resistance tests of large-weight components and higher acceleration. ^ 3 dwg |
