The invention discloses an electromagnetic dark box device for a vibration test of missile-borne data chain equipment. The device comprises an electromagnetic dark box and a fixing frame, wherein theconnection among all assemblies of the electromagnetic dark box, the connection among all assemblies of the fixing frame and the connection between the electromagnetic dark box and the fixed frame adopt a welded mode, so that the strength and rigidity of the electromagnetic dark box are guaranteed, and then the vibration condition generated by a vibration table can be transmitted to the missile-borne data chain equipment in a undistorted manner; a wave absorbing material is adhered to the inner wall of the electromagnetic dark box, a signal channel is formed in a receiving antenna of a rear fixing plate of the electromagnetic dark box, the wave absorbing material is used for shielding and attenuating electromagnetic interference of various frequencies radiated by a vibration working table,and white noise interference existing in the natural environment, and meanwhile, it is guaranteed that electromagnetic waves emitted by the missile-borne data chain equipment are transmitted to the receiving antenna without attenuation through the signal channel, so that a clean testing environment is provided for a power characteristic test of the data chain equipment, then a test result is moreaccurate, and a foundation is provided for testing power characteristic indexes during the vibration test of the data chain equipment.
Description
technical field [0001] The invention relates to the testing technology of electromagnetic wave emission power characteristics of missile-borne data link equipment in a vibrating environment, and in particular to an electromagnetic black box device for vibration testing of missile-borne data link equipment. Background technique [0002] During the research and development, production and delivery process of the missile-borne data link equipment, it is necessary to perform vibration simulation tests in the X, Y, and Z directions on the vibration table, and test the power characteristic indicators of the data link equipment during the test. However, in the actual vibration test, due to the electromagnetic interference of various frequencies radiated by the shaking table and the interference of white noise in the natural environment, the power characteristic index of the data link equipment is not accurate during the vibration test. Therefore, the current domestic During the vib...
