摘　　要：为实现飞轮在额定转速下不松脱,具有核主泵所要求的转动惯量,保证飞轮在额定转速下的完整性的同时能达到在限定转速下的脱落,对国内外各类飞轮结构进行了调查,研究了美国双层脱落式飞轮结构的原理及特点,同时报告了国内外脱落式飞轮结构的发展现状。在结合了各类型飞轮结构的优缺点后设计了全新的核主泵飞轮结构,应用平面应力解析法以及有限元分析选定了合适的过盈量,通过试验验证了此脱落式飞轮的可行性。结果表明:此飞轮结构能够保证额定转速下的完整性,实现临界转速的合理松脱。For the realization of the flywheel under the rated speed without slip, with the moment of inertia nuclear main pump required , by the same time it makes sure that it can fall off under the critical speed. Researches various structure of flywheel abroad and at home, it studies the principle and characteristics of double off flywheel of American. Reportes on the current development of fall-off flywheel structure at home and abroad. It designs the structure of the main pump flywheel. Selects the appropriate amount of interference with the method of plane stress analytic and finite element analysis .The results show that the flywheel structure can ensure the integrity under the rated speed, and the flywheel can slip under the critical speed.
