Review of pyroshock simulation and response prediction methods in spacecraft

The pyroshock environment of satellite-rocket separation is the severest mechanical environment during launching, which is characterized by transient high acceleration and high frequency. While it does not necessarily cause a satellite any structural damage, pyroshock may incur most serious damages on a satellite's precision electronic equipments containing crystals and brittle materials, resulting in either the failure of the entire mission or even catastrophic accidents. Therefore, during the development of a new spacecraft, an accurate prediction of the pyroshock environment and a reasonable specification and determination for components are essential. In this paper, a research review of ground simulation test methods and the pyroshock response prediction is presented, and the technological gap between China and countries highly developed in field is pointed out. In addition to that, according to the requirements of China's domestic space engineering, the main research directions in the pyroshock are proposed.
