Abstract

Provided is a rotary testing platform for a damping loop structure for a guided flying object. The rotary testing platform includes a rotary table mechanism (1), a rotation supporting device (2), an air feed system, and a control system. A support flange (27) on the front end of a rotary support (4) is connected to a rudder moment loading device (5). The center of the rotary support (4) is connected to a compressed air branch pipe (15) through a high-pressure rotary compression ring. A main shaft of the rotary table mechanism (1) and a main shaft of the rotation supporting device (2) are both of hollow structures, and the hollow cavities are communicated with the air feed system. The rotary table mechanism (1) and the rotation supporting device (2) are connected to the control system through a test cable (18). The platform can simulate the rotary state of a flying object that rotates in a reverse course and in an anticlockwise manner, the test precision can reach 1%, and the operation is more intelligent and convenient. All modules are high in integration level. The effective value, the peak value and a corresponding waveform curve of a damping loop of a to-be-tested product can be measured accurately, the state of the damping loop can be determined, and safe running of equipment can be guaranteed.

Description

technical field [0001] The invention relates to an auxiliary inspection technology for a damping loop structure, and belongs to the technical field of IPC international classification G01R measuring electric variables or magnetic variables, in particular to a rotating verification platform for a damping loop structure of a guided flying object. Background technique [0002] In the daily preventive test program, the damping circuit verification test is very important. For example, in the field of power transmission and transformation, the failure of the electromagnetic damping circuit causes the number of capacitive voltage transformers out of operation to account for more than 60% of the total number of failures. Due to the inability to accurately carry out the state analysis of the damping circuit, the electromagnetic part of the capacitive voltage transformer frequently suffers from heat generation, abnormal secondary voltage, and even bursting of the low-voltage fuse, whi...
