Abstract

Though analysis of the blast wave changing law and the basic equation of blast wave overpressure functions in air,blast wave overpressure functions have been simplified. A simplified form of blast wave overpressure function is acquired,and experimental certificated. The results show that the simplified function curve correctly reflects the characteristics of the experimental curve. The blast wave created to simplify the function is reasonable.
