Abstract:In order to solve the hard problem of data measuring and safty control in the impact and damage test subjected to underwater explosion, a kind of underwater explosion test measuring and control system on the sea was built on the basis of the test guarantee platform, the data measuring subsystems of strain, acceleration, pressure, video, image, and so on, were modularly designed. The corresponding test procedure, test security and risk control plan were designed as well. The system was tested on the sea after combined testing on the dock. The reliability of the system and the security of the platform were checked after the test. The anti-impact protective measures worked and the result verified the stability, reliability, safety and controllability of the system, which also revealed that the data collection and storage were realized multi-directionally and multi-elementally. The shortage of the test and the key problems in the coming underwater explosion test were pointed out, which provided strong guarantee support to the impact and damage test of equipment subjected to underwater explosion.
