The meanings and characteristics of theoretical computation method and average radial stress computation method for disk radial burst speed were analyzed. According to the meanings of theoretical computation method

the correction method for disk radial burst speed was put forward on the basd of finite element computational results. By application example

relative to theoretical method's computation result indicates that the correction method has higher calculation precision than the average radial stress method.The calculation precision is improved from 6.6% to less 0.5%. The correction method is more convenient and applicable than theoretical method.
