英文摘要： With the new microelectronic devices widely used in the field of avionics equipment, the avionics equipment failure caused by heavy ion radiation effects has become a civil aviation safety hazard. The advanced airworthiness councils of Europe and the United States have realized the problem of heavy ion radiation effects but without specific solutions. The applicants are requested to identify the malfunction or failure of heavy ion radiation effects, take protective measures to eliminate the malfunction or failure. In this study, a radiation effects simulation test platform is established for the new avionics heavy ion radiation effects, the SRAM -type devices based aviation data bus is taken as a research object, and the fault injection model and techniques with air radiation environment simulation are studied. Based on civil aircraft system safety assessment theory, avionics failure mode and mechanism of radiation effects are researched, radiation hardening technology of avionics and security qualitative and quantitative assessment methods are studied. This study may provide technical support for the airworthiness Bureau to develop the appropriate technical standards and regulatory aviation effects of heavy ion radiation risk, and provide theoretical and technical reference for heavy ion radiation protection an
