Research on the Vibration Response of Cylindrical Vessel under Explosion Shock Wave in Confined Space

Abstract

Abstract The experimental research is carried out on the shock wave vibration response of the cylindrical explosive container under the explosion at the center point. First, a horizontal flat-head cylindrical explosion vessel was designed and the shock wave vibration test placement was carried out; secondly, the explosion shock wave vibration test in a confined space was carried out under different charges; then the vibration conditions at several typical locations were carried out Comparative measurement and analysis of its vibration frequency characteristics. The test results show that the shell vibration acceleration value at the measuring point is related to the charge amount and the distance from the explosion center; the shell vibration frequency close to the middle ring is dominated by the natural fundamental frequency, and as the shell moves away from the center to the ends, The low-frequency vibration gradually increases, and the vibration frequency component of the container head is single, and its main frequency is determined by the natural frequency of the head.
