Abstract: Discussed are several basic problems in the research of digital simulation of SRM structural reliability, such as the aim of the research, the main technical specification, the verification test and the critical technical items. As examples, the simulation process of fiber-reinforced composite case and solid grain of SRM are presented to illustrate the general program of digital simulation of SRM structural reliability.
