Abstract

The invention discloses a data interface for an external pressure test of a sealed cabin. The sealed cabin is formed by processing and mainly comprises a sealed cabin penetrating device (1) and a spiral clamping device (2). One end of a measurement lead wire is connected with an internal measurement point of a carrier type cabin body through a wiring hole in the sealed cabin while the other end of the measurement lead wire is connected with test data acquisition equipment. The invention further provides a corresponding system. According to the data interface and the system, the measurement requirements of the external pressure test of the carrier type cabin body in a sealed environment are met, a real and reliable test state is guaranteed, the test efficiency of the external pressure test of the carrier type cabin body is improved, and the test is promoted to be smoothly performed.

Description

technical field [0001] The invention belongs to the scope of an external pressure test measuring device, and in particular relates to a data interface for an external pressure test of a sealed cabin. Background technique [0002] In the external pressure test task of the carrier model, it involves the collection and measurement of test data in a sealed environment. During the test, firstly, the lower end frame of the test cabin is connected to the steel plate, and the sealing film is used to seal the cabin and the steel plate as a whole, and then the test is applied. external pressure load. [0003] According to the characteristics of the external pressure test conditions, the measuring points need to be arranged inside the cabin, and the measuring wires need to pass through the steel plates. The through hole is connected with external measuring equipment for test data collection and measurement. due to steel plate Due to the existence of through holes, there is a probl...
