Penetrating ammunition can be used to attack enemy underground works, large ships, important bridges and other high-value targets, which has important tactical value. As the core component of all kinds of high-speed penetrating ammunition, high-g accelerometer is the key to achieve accurate explosion point and to reach optimal damage efficiency. Testing and calibration equipment for extreme adverse environment test is an important means to support the development of military products, core devices, reliability verification and evaluation. Western countries impose strict embargo and technical blockaded on our country. This paper summarized the research progress and development trend of high-g accelerometer and extreme environment test equipment at home and abroad, analyzed the difficulties and core problems of this technology in Chinese, pointed out feasible solutions, breakthroughs and research trends, provided reference and basis for the development of high-g accelerometer, extreme environment test and measurement calibration technology.
